How structured browser data changes the way software is built, tested and shipped. This is the canonical archive of the series — written for people who build agents, published on Dev.to, with mirrors on Reddit at r/RuntimeSnapshots.
Runtime Snapshots is an ongoing series about what becomes possible once an agent can perceive a live page as structure rather than pixels. It is written for people who build agents — the reliability, cost, and coexistence problems that show up when software has to act on real, authenticated web applications. New issues publish on Dev.to first and are mirrored to the r/RuntimeSnapshots community.
A browser session as a surface shared by a human and N agents; the hard problem is coexistence, not permission.
