What AI Built catalogs kernels, compilers, operating systems, databases, and other systems projects attributed to coding agents.

Landing page captured for the 2026-11-14 issue.

For: Developers tracking AI-assisted systems projects
Worth noticing: Entries without a public repository remain listed, but are marked unverified rather than treated as confirmed code.

Field notes

The visible list spans kernels, compilers, databases, browser engines, and accelerator kernels, with entries naming a harness and model where the source provides them. Verification is an evidence label: the site says it requires a first-party source and accessible code, while posts or papers without a public repository remain marked unverified. Readers can filter the list by project type, harness, model, difficulty, and verification status.
