- io-pim-discoveryDiscover a provider’s IMAP, SMTP, JMAP, CardDAV and CalDAV services from an email address. The CLI ships as an off-by-default cargo feature.
Every tool is free software, dual-licensed MIT or Apache-2.0.
I/O-free libraries underneath
Every app is a thin frontend over reusable crates. Protocol logic lives in sans-I/O coroutine libraries: no sockets opened, no TLS imposed, no async runtime chosen for you. You drive them with your own I/O: std or no_std, sync or async, desktop or Android.
Free software, kept working against real servers
The code is the cheap part. Keeping it working is what costs, and it costs every year.
- For mail providersYour servers in our test suite, your users set up with one address, in apps under your name.
- For products that handle mailOff Exchange Web Services and basic auth before Microsoft’s deadlines, then kept working.
- For integratorsYour workflows in our test suite, a version line that does not move under you.
Our first partner builds with us an AI-powered desktop client for mail, contacts and calendars, on the Pimalaya stack.
Talk, contribute, build on it
Bug reports, documentation, packaging and code are all contributions, and the CLIs and libraries are made to be built on. Join the community.
