Apache ShenYu vs Certbot
A side-by-side editorial comparison of Apache ShenYu and Certbot — release velocity, themes, recent moves, and the top alternatives to consider.
Apache ShenYu vs Certbot: at a glance
What is Apache ShenYu?
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.
What is Certbot?
Certbot is rebuilding its API around identifiers so certificates aren't only for domain names.
Certbot is on a roughly monthly minor cadence and the defining change in this window is IP address certificate support. 5.3.0 added the --ip-address flag for the standalone and manual plugins and began renaming the API's domain concept to identifier; 5.4.0 extended IP issuance to the webroot plugin. The other visible work is structural: the nginx and apache plugin code moved into the certbot package as extras, the pyOpenSSL dependency is being unwound through a series of deprecations, and certbot.ocsp is scheduled for removal from the public API.

An API gateway that has quietly grown an LLM plugin family — and then stopped shipping.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Certbot
2.5INFRA · APIS
Certbot is rebuilding its API around identifiers so certificates aren't only for domain names.
◆ Current state
Certbot is on a roughly monthly minor cadence and the defining change in this window is IP address certificate support. 5.3.0 added the --ip-address flag for the standalone and manual plugins and began renaming the API's domain concept to identifier; 5.4.0 extended IP issuance to the webroot plugin. The other visible work is structural: the nginx and apache plugin code moved into the certbot package as extras, the pyOpenSSL dependency is being unwound through a series of deprecations, and certbot.ocsp is scheduled for removal from the public API.
◆ Where it's heading
The identifier rename is the tell — Certbot's data model assumed a certificate subject was a domain name, and IP address issuance forced that assumption out of the type system. Expect that refactor to continue reaching further into the plugin API, since get_chall_pref has already changed signature. In parallel the project is shedding dependencies and consolidating packaging: plugins as extras rather than separate distributions, pyOpenSSL functions deprecated batch by batch, and Docker images tracking new Python versions promptly. The releases have become small and predictable, with most content in the Changed and Fixed sections rather than Added.
◆ Prediction
Expect IP address support to reach the remaining plugins, following standalone and manual then webroot, and expect the pyOpenSSL removal to land as a major version once the deprecation cycle completes. Given 5.5.0 already deprecated certbot.ocsp for removal in the next major, that release is the one to watch for breaking changes.
