Datasette Apps: Host Custom HTML Applications Inside Datasette
Simon Willison's Weblog39 days agoNew ToolSimon Willison has launched datasette-apps, a new Datasette plugin that embeds sandboxed HTML+JavaScript applications directly inside a Datasette instance, giving each app live read-only SQL access to the underlying SQLite data. Apps run inside tightly restricted iframes using a combination of the sandbox attribute and injected Content Security Policy headers, preventing untrusted code from accessing cookies, localStorage, or external hosts. The concept originated from Willison's effort to replicate a Claude Artifacts-style experience inside Datasette Agent, before being promoted to a standalone top-level plugin.

Quoting Jeremy Howard on Anthropic's Recursive AI Self-Improvement Contradiction
Simon Willison's Weblog47 days agoEthicsJeremy Howard proposes that labs claiming to slow recursive AI self-improvement should ban themselves from using their top model for frontier research while letting others access it. He argues Anthropic does the opposite — using its best model internally while reportedly blocking others from doing the same — accelerating the frontier and worsening power imbalance. Howard personally favors democratization over slowdown, but his point is about consistency: if you preach restraint, constrain yourself first.
