Datasette 1.0a33 extends the ?_extra= API pattern to queries and rows on the road to 1.0.

“Because API explorer tools are almost free to build now”

Simon Willison released Datasette 1.0a33, extending the JSON API's ?_extra= pattern to queries and rows. The notable AI angle is his workflow: he used Claude Fable 5 in Claude Code for planning and GPT-5.5 in Codex for implementation to build a throwaway API explorer tool, reflecting how cheap AI-assisted tooling has become. It's a minor open-source release rather than a major industry signal.
