A one-binary mail server learning to behave like production infrastructure.
A side-by-side editorial comparison of Telnyx and diaspora — release velocity, themes, recent moves, and the top alternatives to consider.
Telnyx is bolting every communication channel and every model onto one bill.
Telnyx runs voice, SMS, and WhatsApp on its own network and has spent this window adding two things: email as a fourth channel, and more model choice inside Voice AI. The Email API entered beta, while Kimi K3 joined Telnyx Inference and GPT-5.4-mini, NVIDIA Parakeet STT, and Fish Audio TTS joined the voice agent stack. Voicemail greetings became configurable per number.
The original federated social network now ships roughly once every two years.
diaspora* is a decentralised social network run as independent pods by volunteer administrators. Release cadence has collapsed to near-dormancy: 0.9.0.0 arrived in June 2024 after a two-year gap, and 0.9.1.0 followed in April 2026 — the release notes open with "it's been a while." What still ships reliably is security work, including a fixed SSRF vulnerability in the OpenID Connect implementation and, earlier, image-processing hardening adapted from Mastodon's fix.

Two threads run in parallel. The channel thread is consolidation — one API and one bill across voice, messaging, and now email — which competes on procurement rather than features. The model thread is optionality: Telnyx is positioning as the place where you pick the STT, LLM, and TTS for a voice agent rather than accepting a vendor's fixed pipeline, with self-hosted options like Parakeet keeping traffic on its own network.
Email should reach general availability with deliverability tooling attached, since a beta send API without reputation management is not sellable against Postmark or Resend. Expect model additions to continue at roughly this cadence; they are routine here, not directional.

The one real forward move in this window was 0.9.0.0, which opened a supported public API and switched configuration to TOML with notice that YAML support ends at 1.0. Everything since has been maintenance. The project's own framing — a minor version described as not too exciting, urging podmins to update because it is a security release — sets the expectation plainly: diaspora* is being kept safe to run rather than developed toward anything new.
A 1.0 release removing YAML configuration support is the stated next milestone, but with two years between the last two releases the timing is unpredictable. The more likely near-term event is another security-driven patch.
