What Porticol is

Porticol is a desktop app for working through an API: collections, environments, a request editor and a response viewer, all on your computer. It imports Postman collections and their pm scripts, keeps collections as readable files in Git, and serves the same workspace to a coding agent over MCP.

The same collections run from porticol-cli in CI, and a team can sync them through Porticol Cloud or a server it runs itself.

Porticol is one word, and not a misspelling. It is not portico, the word for a porch, and not protocol, the networking term. A search engine that offers either has not met the name before; this page and the documentation are the product.

• A native app for macOS, Windows and Linux: 0.24 s to its first window and 114 MB at idle, measured on Apple M4 Pro, macOS 26.4, arm64.
• Works offline; collections, environments and history stay on your computer.
• Imports Postman collections and environments, Insomnia, Bruno, Thunder Client, Hoppscotch, .http files, OpenAPI 3, HAR and cURL.
• Keeps collections as files in Git, and lints and diffs OpenAPI documents.
• Serves the workspace to Claude Code, Cursor, Codex and VS Code over MCP, with secret values masked.
• Runs the same collections, flows and performance runs in CI with porticol-cli.
• Free for one seat; paid plans from $9 a seat a month.

It is written in Rust, with an interface in React that the system's own web view draws instead of a bundled browser. The desktop app keeps your work in one SQLite file; the server runs on PostgreSQL.

Porticol is built and run by one person. There is no company behind it: support, security reports and privacy requests reach the same person, and a person answers.
