A side-by-side editorial comparison of Apache ShenYu and CircleCI — release velocity, themes, recent moves, and the top alternatives to consider.
An API gateway that has quietly grown an LLM plugin family — and then stopped shipping.
Apache ShenYu's tracked releases run through the 2.7.0.x patch line and stop in November 2025. The consistent thread across those releases is a set of AI plugins accumulating alongside the traditional gateway ones: an AI proxy, an AI token limiter, an AI request transformer, and an MCP server plugin that shows up in the most recent entry through timeout and request-size fixes. The rest of each release is bug fixing and test coverage, with configuration synchronization through Nacos accounting for a recurring share of the defects.
CircleCI ships an MCP server and auto-rollback deployments, moving well past pure CI.
CircleCI has shipped three directional moves in two weeks: a hosted MCP server that gives AI assistants 24 tools to read and act on pipelines, Smart Deployments with automatic monitoring-triggered rollback, and the Machine Runner Orchestrator reaching GA with multi-resource-class autoscaling. The product is no longer just a CI runner — it now spans self-hosted infrastructure management and post-deploy validation. Cursor Origin integration in beta extends that reach into AI-native development environments.

ShenYu is positioning as a gateway for model traffic as well as service traffic, and the pattern is telling — the AI plugins appear first as features and then, one release later, as bug reports, which is what real usage looks like. Rate limiting by token rather than by request is the specific piece that matters, since it is the unit LLM providers actually bill on. Against that, the release notes are undifferentiated pull-request lists and nothing has shipped in the tracked feed for over eight months.
Expect further hardening of the MCP server plugin, which is the newest and least settled of the AI additions. The gap since 2.7.0.3 should be checked against the project's actual activity before drawing conclusions from it.

Cursor Origin integration in beta extends that reach into AI-native development environments.
CircleCI is positioning itself as a control plane for the full software delivery lifecycle, not just CI. The MCP server is the clearest signal: the bet is that AI agents will manage CI pipelines, not just execute them. Smart Deployments targets the CD-to-production gap historically owned by separate tooling like Argo and Spinnaker. If both bets compound, CircleCI competes in a substantially broader market than it has historically occupied.
The next likely move is expanding MCP tool coverage — particularly config generation and test intelligence — and graduating Cursor Origin from beta to GA. Smart Deployments will likely add more monitoring integrations beyond Datadog and Prometheus, with Honeycomb and Grafana Cloud as obvious candidates.
