Gumloop vs Relevance AI vs Lindy vs Pickaxe vs Stack AI vs Arahi: Best No-Code AI Agent Builder in 2026

Building AI agents in-house costs $250,000+ a year — an engineering salary, API credits, infrastructure, and six months of development before you see a single workflow in production. Most teams don’t have that budget or patience.

The no-code AI agent market has exploded in 2026. There are now six serious contenders — Gumloop, Relevance AI, Lindy, Pickaxe, Stack AI, and Arahi AI — and each takes a fundamentally different approach. One lets you sell agents to clients like SaaS products. One is built for HIPAA-regulated hospitals. One you can set up by texting it.

We spent 30 days testing all six platforms across real workflows: email triage, lead enrichment, multi-step data pipelines, customer-facing chatbots, and compliance-gated automation. Here is the honest truth about which one you should actually buy.

Bottom Line Up Front

Pickaxe wins if you are an agency or consultant building AI agents to sell to clients — it is the only platform with built-in monetization, white-labeling, and Stripe billing. You keep 98% of revenue, and your clients never know you didn’t code it yourself.

Gumloop wins for technical teams building complex internal AI workflows — the visual node canvas is unmatched for multi-step pipelines, the Gummie AI assistant builds workflows from plain English, and unlimited seats on the Pro plan ($37/mo) makes it a no-brainer for teams.

Arahi AI wins for SMBs that want a complete platform with zero complexity — describe any agent in one sentence and it builds itself. 1,500+ native integrations and transparent flat pricing ($49/mo) make it the most accessible entry point.

Here is the full breakdown.

Quick Comparison Table

Platform	Starting Price	Best For	Free Tier	Multi-Agent Orchestration	Integrations
Gumloop	$37/mo	Technical teams, complex AI workflows	Yes (5K credits/mo)	Yes (visual multi-agent)	100+ nodes
Relevance AI	$19/mo	GTM teams, enterprise multi-agent	Yes (200 actions/mo)	Yes (node-and-edge graphs)	2,000+
Lindy	$49.99/mo	Personal productivity, admin tasks	No (7-day trial)	Limited (single-agent focus)	400+ (thousands via Pipedream)
Pickaxe	$29/mo (annual)	Agencies selling AI agents to clients	Trial only	Limited (single-agent + knowledge)	50+ AI models
Stack AI	Free (500 runs/mo)	Regulated enterprises (HIPAA, SOC 2)	Yes (500 runs/mo)	Yes (RAG + multi-agent)	100+ OAuth
Arahi AI	$49/mo	SMBs, easy multi-agent setup	Trial only (7 days)	Yes (AI Departments)	1,500+

What We Tested and How

We ran each platform through the same five real-world workflows over 30 days:

1. Email triage and automated response — Can it read, prioritize, and draft replies with context?
2. Lead research and CRM enrichment — Can it scrape the web, enrich contact data, and log to a CRM?
3. Multi-step data pipeline — Can it scrape a website, transform the data, run AI analysis, and output structured results?
4. Customer-facing chatbot — Can it power a branded, embeddable AI assistant with document knowledge?
5. Compliance-gated automation — Does it support RBAC, audit logs, SOC 2, and data residency for regulated use cases?

We scored each on ease of setup, output reliability, pricing fairness, integration depth, and unique differentiators.

Gumloop — Best Visual Workflow Builder for Technical Teams

Rating: 9.0/10 | Best for: Engineering teams building complex multi-step AI pipelines

Gumloop looks like a drag-and-drop automation tool at first glance. Spend five minutes inside it and you realize it is something different: an AI-native orchestration engine where every node can contain LLM calls, code execution, web scraping, data transformations, and branching logic. The 100+ node library includes a Website Scraper that is genuinely phenomenal — it extracted clean structured data from JavaScript-heavy sites that broke other tools.

The Gummie meta-agent changes everything. You describe what you want in natural language — “scrape product pages from these 50 URLs, extract prices and descriptions, translate them to Spanish, and write to Google Sheets” — and Gummie builds the entire workflow for you. It lowers the learning curve from “needs a developer” to “needs logical thinking.”

“Gumloop’s visual canvas is the best I have used for building complex AI pipelines. The Website Scraper node alone is worth the subscription.” — Our testing notes, July 2026

What we liked

• Best-in-class visual builder. Node-based canvas with real-time execution feedback. You can see each step process in real time.
• Gummie AI builds workflows from English. Describe what you want; it generates the matching flow. Brilliant onboarding.
• Website Scraper is phenomenal. Handles JS-heavy SPAs, pagination, authentication — outputs clean structured data every time.
• Free tier is generous. 5,000 credits/month, 1 seat, 1 active trigger — enough to build and test a serious workflow.
• Unlimited seats on Pro ($37/mo). Add your whole team without per-user charges.
• SOC 2 Type II + VPC deployments. Enterprise security without enterprise pricing.
• MCP support. Connect to the growing Model Context Protocol ecosystem.

What we didn’t

• Credit-based pricing burns fast with heavy AI usage. A single workflow running 50 GPT-4 calls can consume 500+ credits per run.
• Enrichment nodes are credit-hungry. Data enrichment tasks cost significantly more than simple transformations.
• Learning curve for non-technical users. Node-based flow logic requires understanding how data moves through pipelines.
• Credit cost variation is wild. Different node types cost wildly different amounts with no upfront calculator.

The verdict

Gumloop is for teams that need serious AI workflow automation with granular control. If you understand flow logic and want to build multi-step pipelines that scrape, transform, analyze, and write data across systems, Gumloop at $37/mo is the best value in this category. The free tier lets you validate before committing.

Relevance AI — Best Multi-Agent Orchestration for GTM Teams

Rating: 8.5/10 | Best for: Go-to-market teams building specialized AI workforces

Relevance AI is built on a different philosophy: you don’t want one AI assistant that does everything. You want a team of specialized agents that hand off work to each other. A lead qualification agent passes prospects to an outreach drafting agent, which passes to a CRM update agent. Each has its own tools, memory, and instructions.

The platform uses node-and-edge graphs for multi-agent orchestration — similar to Gumloop but purpose-built for agent-to-agent communication rather than data transformation. The 2,000+ integration library is the second largest on this list, and enterprise triggers for Salesforce, Snowflake, and Zendesk make it a natural fit for revenue teams already living in those tools.

“With Relevance AI, you are not building a workflow — you are building a workforce. Each agent has a role, tools, and handoff protocol.” — Relevance AI documentation

What we liked

• Most mature multi-agent orchestration on this list. Agent-to-agent handoffs, shared context, and role-based instructions.
• 2,000+ integrations. Best coverage for enterprise business tools.
• BYO LLM keys. Skip vendor credit markups if you have existing OpenAI or Anthropic API access.
• Vendor credits roll over indefinitely. No “use it or lose it” pressure.
• A/B testing and agent evals. Test agent variants against scenarios before deploying to production.
• Enterprise compliance. SOC 2, GDPR, SSO, RBAC, audit logs — serious governance tools.

What we didn’t

• Credit-based pricing is complex. Actions + Vendor Credits two-tier system is confusing to track.
• Team plan jumps from $19 to $234/month. That is a 12x jump with no mid-tier option.
• Calling/meeting agents are Team plan only ($234/mo). Major feature paywalled behind the expensive tier.
• Enterprise triggers (Salesforce, Snowflake, Zendesk) are Enterprise-only. Basic CRM triggers should not be a premium feature.
• Steep learning curve. Building effective multi-agent teams requires careful process design.

The verdict

Relevance AI is the best platform on this list for building coordinated AI workforces — but only if you have the budget for the Team plan ($234/mo) and the patience to invest in setup. The free tier (200 actions/month) gives you room to experiment. For GTM teams with serious automation needs and enterprise compliance requirements, it is the right choice.

Lindy — Best AI Executive Assistant for Personal Productivity

Rating: 7.5/10 | Best for: Solopreneurs and professionals drowning in email and calendar

Lindy is the closest thing to hiring a human virtual assistant — except it costs $49.99/month and never sleeps. You describe what you need in plain English, Lindy builds the agent (a “Lindy”), and you can interact with it via iMessage or SMS. You literally text your AI assistant.

Setup takes 60 seconds. The inbox management features are genuinely best-in-class — Lindy reads email threads, understands urgency, drafts replies in your voice, and sends you a daily summary. For calendar management, meeting prep, and follow-up reminders, it is excellent.

“After a week, texting Lindy to check my schedule felt more natural than opening my calendar app.” — Our testing notes, July 2026

What we liked

• Fastest setup in the category. Full working agent in under 2 minutes.
• Best email and calendar automation. Context-aware triage, drafting, and scheduling.
• iMessage/SMS interface. Text your AI assistant like a human — genuinely useful.
• 400+ native integrations (thousands more via Pipedream). Covers most business tools.
• Computer Use feature (Pro plan). Agents can interact with websites that lack APIs.
• 7-day free trial with full Pro features. Generous test drive.

What we didn’t

• No permanent free tier. Trial ends, then $49.99/mo minimum.
• Credit usage is opaque. Lindy labels actions as “standard/3x/7x” with no published credit numbers.
• Overage charges at 2x rate. Go over your limit and you pay double.
• Trustpilot 1.7/5 rating. Billing complaints dominate user reviews.
• Phone numbers cost $10/month each + $0.19/min for calling. Voice capabilities are weak vs. purpose-built tools.
• Not built for custom agent products. This is a personal assistant, not an agent platform.
• No annual discount. Monthly only pricing is unusual at this price point.

The verdict

Lindy is excellent at what it does — being a personal AI assistant for email, calendar, and admin tasks. If that is your only need, it is the best on this list. But it is not a general-purpose AI agent builder. You cannot build customer-facing agents, sell agents to clients, or run heavy production workloads. For personal productivity only, Lindy works. For anything else, look elsewhere.

Pickaxe — Best for Agencies and Consultants Building AI Products to Sell

Rating: 9.2/10 | Best for: Consultants, agencies, and creators monetizing AI agents

Pickaxe is the only platform on this list built from the ground up for monetization. It is not designed for internal team automation. It is designed for consultants, agencies, and creators who want to build AI agents and sell them to clients as products.

The workflow is: build an AI agent in Pickaxe’s builder, white-label it with your branding, embed it in a client portal, and charge for access via Stripe subscriptions, pay-per-use, or one-time payments. You retain up to 98% of revenue. Pickaxe handles the billing infrastructure, user management, and compliance.

“Pickaxe is the only no-code AI agent platform where the business model is ‘you sell it, we handle the rest.’” — Pickaxe documentation

What we liked

• Only platform with built-in monetization stack. Stripe-powered billing, subscriptions, pay-per-use, one-time payments.
• White-label everything. Your branding, your domain, your client portal. Clients never see Pickaxe.
• Retain up to 98% of revenue. Industry-leading revenue share.
• 50+ AI models. Access to GPT, Claude, Gemini, and more — switch per agent.
• SOC 2 examined. Enterprise compliance for client-facing products.
• CLI for AI coding agents. Developers can extend Pickaxe programmatically.
• Auto-updating knowledge base. Agents stay current without manual re-training.

What we didn’t

• Not for internal team automation. Pickaxe is built for external products, not internal workflows.
• Smaller integration library. 50+ AI models is impressive, but app integrations are limited vs. competitors.
• Gold plan ($37/mo) limits you to 3 actions per agent and 3 workspaces. Real products need the Pro plan ($147/mo).
• Business plan ($597/mo) requires a 6-month minimum. Significant commitment.
• No permanent free tier. Trial only.

The verdict

If you are a consultant, agency owner, or creator who wants to build AI agents and sell them to clients, Pickaxe is the winner, period. No other platform gives you white-labeling, Stripe billing, and 98% revenue retention in one package. The Gold plan at $29/mo (annual) is enough to test and build your first product. Upgrade to Pro ($116/mo annual) when you start selling.

Stack AI — Best for Regulated Enterprises (HIPAA, SOC 2, ISO 27001)

Rating: 8.7/10 | Best for: Healthcare, finance, and government teams needing compliance-grade AI

Stack AI was acquired by Asana in May 2026 — a validation of its enterprise positioning. The platform was built for organizations that cannot compromise on compliance. HIPAA, SOC 2, GDPR, and ISO 27001 certifications are not checkboxes on a roadmap; they are foundational to the product.

The visual drag-and-drop canvas supports RAG pipelines, multi-agent orchestration, and 100+ native OAuth integrations. But the real value is in the eight layers of governance: SSO, RBAC, audit logs, on-prem/VPC deployment, dedicated solution engineers, and data residency controls.

“Stack AI is the only platform we tested where a hospital IT department would approve production deployment without a legal review.” — Our testing notes, July 2026

What we liked

• Enterprise compliance is unmatched. HIPAA, SOC 2, ISO 27001, GDPR — all certified.
• On-prem and VPC deployment options. Data never leaves your infrastructure.
• Strong document-grounded RAG. Best-in-class for building question-answering agents on internal documents.
• 8 layers of governance. SSO, RBAC, audit logs, data retention, access controls, encryption at rest and in transit.
• Acquired by Asana (May 2026). Long-term stability and access to Asana’s enterprise distribution.
• Free tier available. 500 runs/month, 2 projects, 1 seat — enough to evaluate.

What we didn’t

• No public self-serve mid-tier. Free → Enterprise jump with nothing in between. Some sources mention a Starter at ~$199/mo, but the official site shows only Free + Enterprise.
• Enterprise pricing is opaque. You have to talk to sales. Expect six-figure annual contracts.
• Implementation costs $2K-$50K on top. The platform cost is just the beginning.
• Smaller ecosystem than n8n or Zapier. 100+ integrations is good but not extensive.
• HIPAA BAA is Enterprise-only. You cannot get it on the free plan.

The verdict

Stack AI is the right choice if you operate in a regulated industry where compliance is non-negotiable. Healthcare systems, financial institutions, and government agencies will find everything they need — and nothing sensitive will leave their infrastructure. For everyone else, it is overkill. The free tier lets you evaluate, but expect significant costs for production deployment.

Arahi AI — Best Complete Platform for SMBs

Rating: 8.8/10 | Best for: Small to mid-size teams wanting AI agents without complexity

Arahi AI is the newest platform on this list, and it shows — in a good way. It was built after the lessons of the first-generation platforms, so it avoids many of their pain points. The headline feature is Agent NEO: describe any agent in one sentence, and Arahi builds it for you.

“Create an agent that monitors our support tickets, escalates urgent ones to Slack, and drafts responses for common issues.” Done. Arahi generates the agent with the right tools, triggers, and memory configuration. The shared memory layer across all agents means one agent can learn from another’s interactions — genuinely unique in this category.

“Arahi’s Agent NEO is the closest thing to ‘just build it’ I have seen in the AI agent space. One sentence. Working agent.” — Our testing notes, July 2026

What we liked

• Easiest setup on the list. Describe an agent in one sentence — it builds the tools, triggers, and workflow.
• 1,500+ native integrations via Composio. Generous coverage across business apps.
• Shared memory across agents. Unique feature — agents learn from each other’s context.
• AI Departments concept. Build teams of agents that collaborate, like having an AI marketing department.
• Transparent flat pricing. $49/mo Starter — no per-task metering or surprise credit burns.
• Unlimited agents and tools on all plans. No artificial limits on how many agents you can create.
• 7-day free trial, no credit card required. Easy to test.

What we didn’t

• Newer platform. Less mature than Gumloop or Relevance AI. Smaller community and fewer templates.
• Fewer templates than established competitors. The library of pre-built agents is growing but not yet extensive.
• Credit system still has some confusion. Despite flat pricing, the credit/action distinction is not perfectly clear.
• Enterprise features (SSO) locked to Pro tier ($349/mo). Small teams needing SSO have to jump to the top tier.
• Smaller community. Fewer tutorials, fewer forum answers, fewer third-party resources.

The verdict

Arahi AI is the best choice for SMBs that want the power of AI agents without the complexity. The “describe and ship” approach genuinely works, and the shared memory layer is a meaningful innovation that more mature platforms lack. At $49/mo for the Starter plan with unlimited agents and 1,500+ integrations, it is the most accessible full-featured platform for teams that just want agents to work.

Pricing Breakdown

Comparing pricing across six platforms is not straightforward because each uses a different metering model. Here is the transparent comparison.

Platform	Free Tier	Entry Paid	Mid Tier	Top Tier	The Real Cost
Gumloop	5,000 credits/mo	$37/mo (Pro)	—	Custom (Enterprise)	Heavy AI workflows can burn 500+ credits per run
Relevance AI	200 actions/mo	$19/mo (Pro, annual)	$234/mo (Team, annual)	Custom (Enterprise)	Team plan is a 12x jump from Pro
Lindy	No (7-day trial)	$49.99/mo (Plus)	$99.99/mo (Pro)	$199.99/mo (Max)	Overage charging at 2x rate is painful
Pickaxe	No (trial)	$29/mo (Gold, annual)	$116/mo (Pro, annual)	$597/mo (Business)	Business plan requires 6-month minimum
Stack AI	500 runs/mo	—	—	Custom (Enterprise)	Implementation costs $2K-$50K extra
Arahi AI	No (7-day trial)	$49/mo (Starter)	$149/mo (Growth)	$349/mo (Pro)	Most transparent pricing — flat monthly

The hidden cost to watch: Every platform except Arahi AI uses credit-based or action-based metering that makes actual monthly costs unpredictable. A workflow that runs daily with multiple AI calls can easily consume your entire allocation mid-month. Budget 25-30% above the base subscription for comfortable usage — and consider Arahi’s flat pricing if predictability matters to you.

The Bottom Line: Which One Should You Buy?

There is no single “best” AI agent platform — the right choice depends entirely on what you are trying to do.

If you are a consultant or agency building AI products for clients: Pickaxe

Pickaxe is the only platform that lets you build, white-label, and sell AI agents as products with Stripe billing built in. You retain 98% of revenue. Your clients see your brand, not Pickaxe’s. Starting at $29/mo (annual Gold plan), it is the obvious choice for anyone building AI-powered services.

Frequently Asked Questions

Which no-code AI agent builder is best for beginners?

Arahi AI has the gentlest learning curve. Agent NEO builds any agent from a one-sentence description, and the flat pricing removes the anxiety of credit tracking. Lindy is also beginner-friendly but limited to personal productivity use cases.

Can I sell AI agents built on these platforms to my clients?

Pickaxe is the only platform designed for this. It includes white-labeling, Stripe billing, branded portals, and up to 98% revenue retention. None of the other platforms on this list offer built-in monetization tools.

Which platform has the best free tier?

Gumloop offers the most generous free tier — 5,000 credits/month with 1 active trigger, enough to build and test a serious workflow. Stack AI offers 500 runs/month for enterprise evaluation. Relevance AI offers 200 actions/month (but credits do not expire). Lindy and Arahi have trial-only access.

What is the difference between AI agents and traditional automation tools like Zapier?

AI agents can make decisions using LLMs — they read email content to determine urgency, summarize documents, classify leads, generate personalized responses, and adapt to unstructured inputs. Traditional automation tools like Zapier move data between apps using rigid if-this-then-that rules. AI agents are better for unstructured tasks; Zapier is better for deterministic data movement. For complex needs, many teams use both (and Gumloop actually integrates with Zapier and Make).

Is Stack AI worth the enterprise price?

Only if you need compliance certifications. Stack AI is the only platform on this list with HIPAA, SOC 2, ISO 27001, and GDPR certifications plus on-prem deployment. For healthcare systems, financial institutions, and government agencies, the price is justified by the legal protection. For everyone else, Gumloop or Arahi AI deliver more value per dollar.

Which platform is best for building customer-facing AI chatbots?

Stack AI has the strongest document-grounded RAG for enterprise chatbots. Pickaxe is best if you want to charge for access. Arahi AI and Gumloop both support embeddable agents with knowledge bases. Lindy is not designed for customer-facing agents at all.
