Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Plivo and Xurrent — release velocity, themes, recent moves, and the top alternatives to consider.
Plivo's CPaaS hygiene work — but the feed is now over a year stale.
The most recent entry is from January 2025, and the rest land between August 2024 and November 2024. The visible work covers CPaaS table-stakes: dynamic usage-based pricing, automated India-number activation, self-service security/profile management, expanded CNAM coverage, voice-invoice transparency, and Verify API parameter additions for branded auth flows.
Sera AI crosses from assistant to autonomous agent while the ITSM core keeps its monthly grind.
Xurrent ships on a disciplined monthly cadence, and the last quarter splits cleanly in two. One half is steady ITSM plumbing — shared tags across Requests, Problems, Workflows and Projects, CMDB reconciliation that a human can actually read, iPaaS connectors, self-service reservations. The other half is Sera AI, which moved from a chat widget to a configurable studio and then, on 10 July, to two agents that act without a person in the loop.

What's in the feed is a steady but unglamorous platform-broadening cadence — geo expansion (India), regulatory plumbing (CNAM, toll-free verification), and pricing flexibility — with no AI, no agentic-voice, no LLM-meets-telephony moves. The bigger signal is the silence: a 16-month gap between the last entry and now, which either means the changelog has moved or the public-facing release stream has gone quiet.
If Plivo is still shipping, the next directional move would almost certainly involve AI voice agents or LLM-powered messaging — every CPaaS peer (Twilio, Vonage, Telnyx) has made that pivot. The absence of any such signal in this batch is consistent with a feed that's no longer the primary changelog surface; the next confirmation will be either a new release stream appearing or a long-overdue entry breaking the silence.

The two tracks are converging rather than running in parallel. Knowledge article readiness, CI location hints and reconciliation legibility are not standalone features — they are the data-quality preconditions an agent needs before it can be trusted to close a request. Xurrent is building the substrate first and letting Sera consume it, which is why the agent work has landed without the usual rollback noise. Agent Designer success metrics suggest the next constraint is proving the agents work, not shipping more of them.
Expect the agent count to grow slowly and the governance surface around it to grow faster — more Golden Set tooling, more per-agent success reporting, and tighter scoping of which request types an agent may close unaided.
