What is Beeper?

Beeper stopped aggregating apps and started merging the people inside them.

The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.

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.

3.8

Beeper stopped aggregating apps and started merging the people inside them.

◆ Current state

The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.

◆ Where it's heading

Two tracks run in parallel. Parity work is making Beeper safe to use as the only client, and for the major networks it is close to finished. On top of that, the product is starting to add things no native app can do: cross-network chat merging, in-chat AI models, a unified requests folder. The public call for third-party bridges suggests network coverage is increasingly a community responsibility rather than an in-house roadmap item.

◆ Prediction

With conversations merged across networks, unified contacts and cross-network search are the natural follow-ons — the organizing primitive shifts from the chat to the person.

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.
