Fonoster vs Revolt: at a glance
What is Fonoster?
Fonoster ships four releases in a day to make linking a Twilio number a single step.
Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.
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.

Fonoster
6.3COMMS
Fonoster ships four releases in a day to make linking a Twilio number a single step.
◆ Current state
Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.
◆ Where it's heading
After rebuilding its SIP and media edge and defaulting to HTTPS in the 0.31 to 0.33 run, Fonoster is now working on onboarding, using Twilio as the way to bring an existing number. The release rate stays very high and breaking changes still land in minor versions.
◆ Prediction
Expect the same number-linking flow for other carriers, or more Numbers page work; the entries only cover Twilio so far.
Revolt
2.5COMMS
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.
