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.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.

SpecialistPowerful enterprise-wide search and knowledge discovery across apps, but lacks Notion's flexible doc creation.

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.
Superior block-based typography and mobile note-taking experience, but fewer robust database and automation features.

SpecialistExcellent developer-focused documentation and Git synchronization, but lacks general database and task management.
Built-in AI agents and automated workflows, but less refined document editing interface.

SpecialistNetworked object-based knowledge management, but less suited for traditional folder hierarchies and task boards.
