AI agent builders:
the alternatives, compared
Workflow automation tools, open-source LLM app builders and enterprise agent platforms all call themselves agent builders now. This list sorts out which is which.
What to look for
- Where the agent runs once it is built: a chat channel your customers use, a schedule, an API, or only inside the builder.
- What it can reach: your documents, any HTTP API, custom code, MCP servers — and whether a person can approve a step before it runs.
- Self-hosted or hosted: owning the infrastructure is control and work; a hosted platform is neither.
- How usage is billed — your own model keys, credits, executions or seats.
