Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.
Design, test, and govern APIs — now with AI agents in the loop
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.
SpecialistIntegrates API testing and development directly inside your code editor, but lacks Postman's dedicated workspace collection management and documentation publishing.
SpecialistExcels at autonomous multi-file code generation and repository-wide understanding, but is not purpose-built for manual API endpoint testing.
Unmatched ecosystem of app connectors and reliability, but significantly more expensive and lacks n8n's self-hosting freedom.
#3No-code builder for custom AI agents and workflows
Free / Open-sourceOpen-source control plane for orchestrating coding agents
SpecialistAutomates end-to-end testing using plain language agents, but lacks Postman's manual debugging and environment variable management tools.
Free / Open-sourceOutstanding open-source visual canvas for RAG pipelines and LLM agents, but less suited for general API integrations.
SpecialistMultiplayer AI where people and agents work side by side
Turn one prompt into live business apps, AI agents and automated workflows
Powerful visual builder specifically tailored for complex AI agent workflows, but less mature for traditional enterprise automation.
SpecialistOffers superior test case management and CI integration for QA workflows, but lacks native API request crafting and mocking tools.
SpecialistDeveloper-first integration platform with granular code control, but lacks n8n's visual node-based workflow builder.
