Pylon: AI Sessions as Source Code

buildpylon.com Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

Pylon traces AI coding sessions, turns their transcripts into searchable context, and lets engineers load past work into a new agent run.

Landing page captured for the 2026-09-04 issue.

Field notes

The site says it works from session files that AI agents already write to disk, avoiding an instrumentation step. Its examples are presented as named, finite artifacts rather than abstract case studies: meridian has 218 turns, northgate has 402, and each session can be loaded as context for a subsequent run. Publication is described as selective, with local secret stripping and an exact diff available for review before sharing.
