An AI agent platform vs custom AI agents you own
Subscribe to an AI agent platform when someone on your team will build and maintain the agents, the jobs are simple, and you are comfortable with your data on the platform and a bill that follows usage: Lindy, Zapier Agents, Gumloop and Make all bill in credits or activities, and the work pauses when the allowance runs out. Pay to have custom agents built when the work is specific to your business, nobody has time to build it, and you want to own the agents, the data and the code. We, Modern Mustard Seed, build the second kind: a crew of Claude agents in your own Anthropic account and database, run by us every month. Gartner predicts over 40% of agentic AI projects will be canceled by the end of 2027, due to escalating costs, unclear business value or inadequate risk controls, so whichever you choose, start with one job you can measure.

|---|---|---|
| Who builds the agents | You do, with templates and a helper: Lindy teaches itself skills you show it once, Zapier Agents has Copilot and templates, Make and n8n use visual builders, and Gumloop is built for non-engineers. Relevance AI embeds a deployment team to get you live, then trains your team to build. | We do, from your Workflow Map and a library of agent templates, and we write a new agent when a job fits none of them. |
| Where your data lives | On the platform: Zapier on AWS in the United States, n8n Cloud in Frankfurt, Make in US or EU data zones. n8n can run on your own servers, and Gumloop Enterprise can deploy in your own cloud. | In your own Anthropic account and a database project in your name, from the first day. |
| How it bills | By usage: Lindy per active user with pooled credits, Zapier Agents by activities, Gumloop and Make by credits, Copilot Studio by Copilot Credits, n8n by workflow executions. | A set monthly package, quoted after a discovery call. Your card pays Anthropic for model usage directly, with no markup from us. |
| When the allowance runs out | The work pauses: Lindy pauses credit-using actions until credits reset, Gumloop agents stop unless pay-as-you-go is on, and Make scenarios stop until credits are added. | You set a spend cap in your own account, and the monthly report shows usage against it. |
| Approvals and control | Varies by platform. Lindy holds anything with outside impact for approval. | You sign an Authority Matrix: what each agent may do alone, what waits for a person, and what it may never touch. |
| If you leave | Your agents are built in the platform. n8n is the exception: its Community Edition runs free on your own servers. | One export downloads every agent definition, test and the full audit log; the Desk code and hosting move to your accounts, and you revoke our access. |

When an AI agent platform is the better choice
- Someone on your team enjoys building automations and will maintain them.
- The jobs are simple and repeatable, such as routing a form or summarizing an inbox.
- You already work in Microsoft 365, Zapier or Make and want agents where your work already is.
- You want to try agents this week on a free or low monthly plan.
When we are the better choice
- Nobody on your team has time to build and maintain agents.
- The work is specific to your business and touches customers or money, so it needs approvals and an audit log.
- You want the agents, the data and the code in your own accounts, with no platform to leave.
- You want someone accountable for the results every month.
Which one fits you
Pick: Platform
A solo consultant who wants inbox triage
One simple job the owner can build in an afternoon.
Pick: Custom
A 20-person service company that wants intake, follow-ups and reporting run every day
Several jobs that touch customers, with approvals and a monthly report.
Pick: Platform
A team already paying for Microsoft 365 Copilot
Copilot Studio builds internal agents inside a stack it already pays for.
Pick: Custom
An owner who wants the agents and data in accounts in their own name
Ownership is the point, and nothing has to be moved off a platform later.
Talk it through before you subscribe.
One call about your week, and a set package price if custom agents are the better path.
Book a Discovery CallCommon questions
Should a small business use an AI agent platform or have custom agents built?
+
Use a platform if someone on your team will build and maintain the agents and the jobs are simple. Have custom agents built if the work is specific to your business, touches customers or money, and nobody has time to build it, especially if you want to own the agents and the data.
What happens when an AI agent platform runs out of credits?
+
Per each platform on October 26, 2026: Lindy pauses credit-using actions until credits reset or you top up, Gumloop agents stop unless pay-as-you-go is switched on, and Make scenarios stop until credits are added.
Can I run AI agents on my own servers?
+
Yes, with n8n: its Community Edition is free to self-host, and its Business plan runs only on servers you manage. Gumloop Enterprise can deploy inside your own AWS, Azure or Google Cloud. Modern Mustard Seed installs agents in your own Anthropic account and database.
Who builds custom AI agents for small businesses?
