What is Revolt?

Revolt swaps Tenor for its own Gifbox, pulling GIF delivery in-house.

Revolt is an open-source, self-hostable chat platform competing in the Discord-alternative space. The one visible release, v0.13.8, replaces Tenor (Google's GIF service) with Gifbox, a GIF platform the project now runs itself. With only a single changelog entry available, the broader release cadence isn't observable from this data.

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.

Revolt vs Stalwart: editorial side-by-side

R
Revolt

2.5

Revolt swaps Tenor for its own Gifbox, pulling GIF delivery in-house.

◆ Current state

Revolt is an open-source, self-hostable chat platform competing in the Discord-alternative space. The one visible release, v0.13.8, replaces Tenor (Google's GIF service) with Gifbox, a GIF platform the project now runs itself. With only a single changelog entry available, the broader release cadence isn't observable from this data.

◆ Where it's heading

Owning the GIF layer instead of leaning on Tenor fits the pattern of a self-hosting-first project reducing third-party and Google dependencies. It points toward more of the messaging stack being brought under the project's own control over time.

◆ Prediction

Expect follow-up work hardening Gifbox (search quality, content moderation, self-host configuration). With only one entry visible, anything beyond that is unclear from the available data.

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.
