The best AI agent builder for business is rarely the one with the lowest entry price, because none of the seven platforms below bills in the same unit. Gumloop and Lindy sell credits, Relevance AI actions, n8n executions, Dify message credits, Zapier Agents activities, and Microsoft Copilot Studio Copilot Credits. Each unit converts to "one agent run" at a different rate, and that conversion, not the plan price, decides what the agent costs once it runs every day.
This article prices all seven at entry level and at roughly 10,000 runs a month, then lists the second-invoice line items. Prices were verified on each vendor's pricing page in September 2026. Stackbinary builds custom AI agents, the "have it built" route discussed at the end.
Best AI agent builder for business: 7 platforms at entry price and at 10,000 runs
The 10,000-run column assumes a mid-complexity agent with three tool calls and two model calls per run on a standard model. Agents that loop over tools cost several times more.
| Platform | Billing unit | Entry price | About 10,000 runs a month | Data residency |
|---|---|---|---|---|
| Gumloop | Credits (1 base plus per node; standard AI call 2, advanced 20) | Free 5,000 credits; Pro $37/mo, 20,000 credits | About 50,000 credits, beyond Pro; Enterprise quote | US; VPC on Enterprise |
| Lindy | Credits per user (simple step 1 to 3, advanced model 10) | Plus $29.99/user/mo, 3,000 credits | 30,000 to 100,000 credits: one to three Max seats ($199.99, 35,000 credits each) | US; HIPAA BAA on Enterprise |
| Relevance AI | Actions plus vendor credits for LLM | Pro $29/mo (2,500 actions); Team $349/mo (7,000 actions) | About 30,000 actions: Team plus top-ups at $40 per 1,000, about $1,269 plus LLM | Not published; confirm in contract |
| n8n Cloud | Workflow executions, unlimited steps | Starter €20/mo (2,500 executions, annual) | Pro €50/mo annual or €60 monthly (10,000 executions) | EU, Frankfurt |
| n8n self-hosted | None (community edition) | Free plus a $20 to $50/mo server | Same server; LLM tokens direct | Anywhere |
| Dify Cloud | Message credits (only for Dify-supplied models) | Professional $59/mo (5,000 credits); Team $159/mo (10,000) | Team $159 with Dify models, or Professional $59 plus your own model keys | AWS US-East |
| Dify self-hosted | None (community edition) | Free plus a server | Server plus LLM tokens direct | Anywhere |
| Zapier Agents | Activities (each tool use, search or knowledge query) | Free 400 activities; Pro $50/mo for 1,500 | About 30,000 activities; Enterprise quote | US |
| Copilot Studio | Copilot Credits (generative answer 2, agent action 5, tenant grounding 10) | $200/mo per 25,000-credit pack, or $0.01 per credit | About 70,000 credits: three packs ($600) or about $700 pay-as-you-go | Microsoft 365 tenant region |
The two open-source builders cost the same at 10,000 runs as at 100, because the billing unit is a server. The credit-based builders cross into four figures somewhere between 2,000 and 5,000 runs a month, the volume of one agent on one inbound channel.
Platform by platform
Gumloop
Gumloop is the most polished visual builder in the group and the most sensitive to model choice. A run costs 1 credit plus each node; most native nodes are free, a standard AI call is 2 credits and an advanced model call 20. Pro at $37 a month buys 20,000 credits and unlimited seats, about 4,000 mid-complexity runs. Past that, pricing is an Enterprise conversation, and the 8 percent orchestration fee listed on Pro is easy to miss.
Lindy
Lindy prices per user and pools credits across the workspace: Plus at $29.99 for 3,000 credits, Pro at $99.99 for 15,000, Max at $199.99 for 35,000, with no free tier since 2026. Simple steps cost 1 to 3 credits and advanced-model steps 10, so the same agent can cost 3,000 or 100,000 credits a month depending on the model behind each step.
Relevance AI
Relevance AI splits the meter in two: actions (each tool execution) and vendor credits (LLM spend on its included models). Pro at $29 a month includes 2,500 actions and $20 of vendor credits, Team at $349 includes 7,000 and $70; top-ups are $40 per 1,000 actions. The public pricing page now leads with the Enterprise plan, so confirm self-serve availability before planning around it.
n8n, cloud and self-hosted
n8n bills per workflow execution with unlimited steps inside each: a 40-node agent run and a 2-node run cost the same execution. Cloud Starter is €20 a month for 2,500 executions and Pro €50 for 10,000 on annual billing (€24 and €60 monthly), hosted in Frankfurt. The community edition self-hosts free on a $20 to $50 VPS, with model tokens going straight to your provider. We compared the two routes in n8n vs Zapier.
Dify
Dify is the open-source builder aimed at LLM applications: RAG pipelines, chat agents and workflow apps with a knowledge base attached. Cloud Professional is $59 a month with 5,000 message credits and Team $159 with 10,000, but credits apply only to Dify-supplied models; with your own API keys the plan is a seat and storage fee. The community edition self-hosts free.
Zapier Agents
Zapier Agents counts an activity each time an agent uses a tool, searches the web or queries a knowledge source, so one instruction that researches ten leads can spend thirty activities. Free includes 400 a month and Pro $50 for 1,500, separate from the standard Zapier task plan. It fits agents that trigger existing Zaps, not agents that think in loops.
Microsoft Copilot Studio
Copilot Studio bills Copilot Credits at $200 per pack of 25,000 a month, or $0.01 each pay-as-you-go. A generative answer is 2 credits, an agent action 5 and tenant graph grounding 10; Microsoft's own example of a support agent serving 900 customers a day comes to about 7,200 credits. Usage by Microsoft 365 Copilot licensed employees is included, which makes it the cheapest option for internal agents in a Microsoft tenant and an expensive one for public-facing volume.
The hidden line items
LLM tokens. Gumloop, Lindy and Copilot Studio fold model cost into credits at a markup; Relevance AI splits it out; n8n and Dify pass it to your provider. At 10,000 runs a month the raw token cost on a standard model is typically $30 to $150, so the credit markup is the largest hidden line.
Seats and controls. Lindy bills per user; Dify Professional caps at 3 team members. SSO, audit logs, VPC hosting and HIPAA BAAs sit on Enterprise tiers everywhere except n8n Business (€667 a month) and the self-hosted editions.
Overage behaviour. Lindy pauses when credits run out; Copilot Studio disables custom agents at 125 percent of prepaid capacity; n8n Business sells extra executions in €4,000 buckets.
When a builder is enough, and when to have the agent built
A builder is the right choice when the agent lives inside one or two SaaS tools, runs under a few thousand times a month, and nobody needs it to survive a vendor's pricing change. That covers most internal assistants, inbox triage and lead enrichment. AI agent vs chatbot sets out where the harder cases start: an agent that books, refunds or changes records needs error handling the builders were not designed for.
Having the agent built starts to pay when the run count is in five figures, when the agent must read and write systems the builders do not integrate cleanly (an ERP, a proprietary database, a telephony stack), or when the credit bill has become a monthly budget question.
Owning the agent instead of renting the credits
Stackbinary offers the built route through its AI development service, so weigh this section with that in mind. For low volume with no integration needs, a builder above is the right answer. Owning makes sense on four points.
Full data autonomy. Prompts, retrieved documents, customer records and every run's logs live in your own system and cloud region, not in a vendor's tenant.
Only the features you use. A credit or seat plan bills you for a bundle: connectors you never call, seats you never fill, markup on every model step. An owned agent carries the workflows you actually run and nothing else, at the raw token and hosting cost.
Your own system, our team managing it. Owning does not mean staffing an engineering team. Stackbinary builds the agent and runs it: hosting, monitoring and model updates as providers ship them.
Lower cost and fast delivery. Fixed-price proposal within 48 hours, 55+ shipped products, delivery in weeks, IP assigned to you on payment. Builds are SOC 2-aligned and HIPAA-ready, so the Enterprise-tier controls above are part of the delivery.

FAQ
What is the best AI agent builder for business?
For internal assistants at low volume, Gumloop or Lindy; for workflow agents with heavy run counts, n8n self-hosted; for LLM applications with a knowledge base, Dify; for agents inside a Microsoft tenant, Copilot Studio.
How much does an AI agent builder cost?
Entry plans run from free to $59 a month. At roughly 10,000 mid-complexity runs a month, n8n Cloud Pro costs €50, Dify Team $159, Copilot Studio about $600 to $700, Relevance AI about $1,269 plus LLM spend, and Gumloop and Zapier Agents move to Enterprise pricing.
Is n8n cheaper than Zapier Agents for AI agents?
Yes at any meaningful volume. n8n bills per execution with unlimited steps, so a 10,000-run month is €50 on Cloud Pro or a server self-hosted; Zapier Agents bills per activity, and 10,000 runs at three activities each is 20 times the Pro allowance.
Which AI agent builder offers EU data residency?
n8n Cloud hosts in Frankfurt, and n8n and Dify can be self-hosted in any region. Copilot Studio follows the Microsoft 365 tenant region. Gumloop, Lindy and Zapier Agents run on US infrastructure at self-serve tiers; Relevance AI does not publish regions.
