A side-by-side editorial comparison of Apprise and Courier — release velocity, themes, recent moves, and the top alternatives to consider.
The final v1.x release slipped by one patch, but the v2 deadline stands.
Apprise is a Python notification library that fans a single call out to more than 150 services. Weighted tagging in v1.11 turned that fan-out into ordered delivery with fallback, and the releases since have been service accretion and bug clearance. v1.13.0 was announced as the last of the v1.x line; v1.13.1 has now shipped anyway, adding Signalgrid and Lauther support and fixing a memory-backed attachment failure, with the maintainer repeating the end-of-line notice and adding that he means it this time.
Courier is turning its notification API into a full messaging orchestration platform.
Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.

The v1 line is being closed out in patches rather than stopped cleanly, which is the normal shape of a maintainer-led project absorbing community pull requests faster than it can cut a major version. The ask to downstream projects has not changed — pin to >=1.0.0,<2.0.0 — and v1.x is stated to keep security support for a year or two after v2 lands. What v2 actually breaks is still not described in any of these entries.
The next release is likely another v1.x patch of the same shape — community service plugins plus attachment and protocol fixes — unless a v2 alpha appears first. Nothing in these entries indicates which.

Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.
The build order is clear: ship the orchestration core first (Journeys, Design Studio, the MCP-aware CLI), then make it production-grade for larger teams. The last quarter is about optimization and governance — experiments, custom environments, decoupled routing — rather than net-new channels. AI is being threaded in as a feature, like localization, not a headline product.
Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.
