What is Stalwart?

Stalwart is chasing mail RFCs and its own storage layer at the same time

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

What is Tinode?

An open-source chat server in steady maintenance while reactions sit in alpha

Tinode's release stream is dominated by dependency upgrades and bug fixes across the 0.25.x line — a gRPC auth-level fix, the Postgres driver moved to v5, AWS to v2. The last substantive user-facing work was pinned chats, subscriber counts and a system-default UI mode in late 2025. A 0.26.0 alpha exists on a reactions branch but has not converged.

Stalwart vs Tinode: editorial side-by-side

S5.0

Stalwart is chasing mail RFCs and its own storage layer at the same time

◆ Current state

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

◆ Where it's heading

Two threads run through every release. One is RFC coverage across IMAP, JMAP, CalDAV and WebDAV, implemented close to the specification including drafts. The other is a long tail of protocol-conformance fixes, many of them cases where JMAP and IMAP disagreed about the same state. The newest release adds a third: memory and scheduling limits, which is what a server codebase starts doing when deployments get large enough for defaults to hurt.

◆ Prediction

Expect continued RFC additions across the JMAP and IMAP surfaces, with more of the storage-tuning work that v0.16.18 started as RocksDB deployments scale.

An open-source chat server in steady maintenance while reactions sit in alpha

◆ Current state

Tinode's release stream is dominated by dependency upgrades and bug fixes across the 0.25.x line — a gRPC auth-level fix, the Postgres driver moved to v5, AWS to v2. The last substantive user-facing work was pinned chats, subscriber counts and a system-default UI mode in late 2025. A 0.26.0 alpha exists on a reactions branch but has not converged.

◆ Where it's heading

Development is consolidation-shaped: the maintainers are keeping the 0.25 line current and correct rather than opening new surface. Performance work in push dispatch and intra-cluster buffers suggests attention on deployments running at size. The reactions branch is the only visible feature bet, and it has been in alpha since January.

◆ Prediction

The next meaningful release is most likely 0.26.0 carrying reactions out of alpha, but the alpha has sat untouched in the window, so a date is not something the entries support.
