Workflow
From import to verified response
Reconn is built for engineers who already work in collections and repositories. Start from what you have and get to a verified result in a few steps.
- 01
Import or capture
Bring a Postman Collection v2.1, or record a live site into requests you can edit and re-run.
- 02
Send with real TLS
Use environments, cURL, and per-request timeouts. Certificate verification is on by default and secrets stay in the local vault.
- 03
Test and explain
Generate positive, negative, boundary, contract, and security cases. Link a repository to get Explain and Report.
Nothing syncs to our cloud
Collections, request history, environments, and the encrypted secret vault stay in the desktop app on your computer. The website only serves downloads and signed update metadata — not your API data.
FAQ
Common questions
Straight answers about what Reconn does, what it stores, and what it costs.
What is Reconn?
Reconn is a desktop API client for macOS and Windows. It imports and exports Postman Collection v2.1, sends real HTTP requests, generates deterministic tests, records live sites with Site Capture, and explains linked code with Deep Explain and Report Center.
Does Reconn use an LLM to generate tests?
No. Reconn generates positive, negative, boundary, contract, and security test cases from deterministic rules, so the same input always produces the same tests. Cursor and Claude Code adapters are optional and only power the code-aware features.
Can I import my Postman collections?
Yes. Reconn imports and exports Postman Collection v2.1 and shows a compatibility report that lists anything it cannot represent. Imported Postman scripts are kept as metadata and are never executed automatically.
Where does Reconn store my secrets?
Tokens and passwords are stored in an app-local AES vault on your machine, not in the OS Keychain. TLS certificate verification is on by default.
Does Reconn save my data in the cloud?
No. Collections, request history, environments, and secrets stay in the desktop app on your machine. The website only hosts downloads and signed update metadata — it does not store your API workspace.
Which platforms does Reconn support?
macOS (a universal DMG for Apple Silicon and Intel) and Windows (an x64 installer). Signed releases update automatically inside the app.
Is Reconn free?
Reconn is in open beta and is free to download and use through 2 November 2026. Pricing will be announced later.
How do I send feedback?
Use the Feedback page on this site. Bug reports and feature ideas both help during the open beta.
What is Site Capture?
Site Capture records a live website's fetch/XHR calls, documents, and images while you browse, scores each page for SEO, AEO, and GEO, and builds a reviewable collection you can edit and re-send.
