About
Ironcall is an API client that stays out of your way. Fast to open, fast to use, and built to last. No forced subscriptions, cloud lock-in, or unnecessary complexity.

Postman was the obvious choice for years. Then it got slower, more cloud-dependent, and started gating basic features behind a login wall. We found ourselves fighting the tool instead of building with it.
Existing alternatives either lack collaboration entirely or replicate the same top-heavy model. We wanted something different: a client that is genuinely fast, works offline by default, and treats your data as yours.
Ironcall is the tool we wanted to use. We think a lot of developers feel the same way.
Every feature works without a network connection. Sync is opt-in, not a requirement.
Collections live on your machine. When sync is enabled, data is end-to-end encrypted and stored on EU servers only.
Telemetry is opt-in and anonymous. No forced accounts, no paywalled basics, no surprise price hikes.
Ironcall is built with Rust and Tauri. It launches in under a second and stays responsive under load.
All server infrastructure runs in the EU. No data crosses jurisdictions without your knowledge.
Team sync uses CRDTs, the same technology behind modern collaborative editors. No conflicts, no last-write-wins.
Ironcall is built on Rust and Tauri v2, with a Solid.js frontend. The same Rust core powers both the desktop app and the CLI, so behaviour is consistent across interfaces.
