Rewriting a 20‑year‑old Python library

The little client that could (and did)

Way back in 2005 blogs were people’s megaphones and comment boxes were spam magnets. Enter Akismet, the web service that checked user content for junk and kept many a blog readable. It has been reported that Michael Foord wrote a compact Python client called akismet shortly after the service launched; he published five releases and the package quietly became one of those tiny, indispensable tools lots of projects rely on. It has also been reported that Foord was lost at the beginning of 2025 — a bitter moment for a community that notices when the people behind the plumbing disappear.

Maintenance, modernization, and handing off the keys

In 2015 the project changed hands. The current maintainer met Foord at a conference, offered to take over, and got a GitHub repo and publishing access. They ported the code to run on both Python 2 and 3, simplified configuration (leaning on 12‑factor patterns and environment variables), and swapped the clumsy stdlib HTTP stack for requests; akismet 1.0 followed in 2017. Small updates trickled out for years — including the inevitable Python‑3‑only cutover in 2020 — until a larger rethink began in 2024.

Why rewrite a working library?

Because sometimes “working” isn’t good enough. The maintainer says one clear motivation was supporting a specific Akismet API capability: historically the client’s comment-check call always returned a bare bool, which hid richer server-side detail. So they embarked on a complete rewrite to expose that functionality and modernize internals, finishing the work a few months ago. The lesson? Even two-decade‑old utilities need fresh air now and then — and a small, well‑maintained library can matter a lot to the web that still runs on them.
