Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
A side-by-side editorial comparison of Tinode and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
Self-hosted chat platform shipping steady catch-up features and ops cleanup.
Tinode is an open-source, self-hosted messaging server with maintained Web, Android (Tindroid), and iOS (Tinodios) clients. The release cadence is regular (multiple tags per month), and the recent body of work is split between small bug fixes, infrastructure tuning (CORS, MySQL/Postgres DSN handling, Docker image fixes, healthchecks), and feature catch-up that brings the UX nearer to commercial chat apps — pinned chats, dark mode, subscriber counts, send-on-Enter, in-call messaging. An alpha for message reactions is in flight.
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.

An alpha for message reactions is in flight.
The project is in steady-state maintenance with one visible directional push: catching up on the UX features that mainstream chat apps have had for years. Reactions are the next concrete step. Bug fixes and ops touchups dominate the in-between releases, which is healthy for an open-source server that runs in self-hosted production deployments.
v0.26.0 will ship reactions as the headline feature. Threads, richer notifications, or moderation tooling are the natural next catch-ups — anything that further closes the gap with Slack/Matrix/Element on the UX surface without expanding the protocol surface too aggressively.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
The work points toward production maturity: closing JMAP spec gaps, adding high-availability primitives (Redis Sentinel coordination), and tightening TLS, DANE, and encryption. Stalwart is positioning itself as a standards-faithful, deployable alternative to legacy mail stacks rather than chasing new user-facing features.
Expect continued point releases that finish protocol conformance and expand operational features—high-availability backends, certificate handling, and encryption options—rather than a major feature pivot.
