Catalog
Systems projects written with coding agents.
Kernels, compilers, operating systems, databases, emulators, browser engines, GPU kernels, and TPU kernels. Each entry names the harness and the model, and links the README, post, or paper that says an agent wrote it.
Verified means we can open a first-party source and the code. A blog post or paper with no public repository stays in the list and is marked unverified. Repo URLs, model names, and benchmark numbers are copied from the source. Add or fix an entry with a pull request.
17 projects
Ginux
A Rust research kernel, later a userspace Linux-compatibility kernel, built with OpenAI Codex under human-directed architecture and acceptance gates.
MaxKernel
A multi-agent system that generates and tunes high-performance TPU kernels, evaluated with Gemini 3.1 Pro and released under Google's accelerator-agents repository.
Antigravity OS experiment
Google's official Antigravity 2.0 demo in which a team of agents on Gemini 3.5 Flash built a functional OS that could run FreeDoom, from a single prompt.
Rabbit
A from-scratch Linux-ABI-compatible x86_64 kernel in Rust, written by an AI agent against human-set milestones, with OpenCode commit trailers.
minisqlite
A Rust reimplementation of SQLite's SQL dialect, planner, executor, transactions, and on-disk format, published by Cursor.
FastRender
An experimental Rust browser engine developed as part of Cursor's research into collaborative parallel AI coding agents.
Cursor NVIDIA kernel optimizations
Kernels produced by Cursor's multi-agent system in a collaboration with NVIDIA, reported to reach a 38% geomean speedup on 235 Blackwell problems.
one-agent-one-browser
A from-scratch HTML/CSS browser in Rust, built in about three days by one human directing one Codex agent, with no third-party Rust crates.
Claude's C Compiler (CCC)
A from-scratch, dependency-free C compiler in Rust, written by parallel Claude Code agents running Claude Opus 4.6, capable of building Linux 6.9 and other large C projects.
JSSE
A from-scratch JavaScript engine in Rust that the author says was built entirely by Claude Code and became the first engine to pass 100% of test262 non-staging tests.
VibeSQL
A Rust SQL database the authors describe as 100% AI-generated, built with Claude Code and the Loom orchestration tool, with public SQL conformance dashboards.
vibix
An experimental Rust x86_64 kernel built almost entirely by Claude and Cursor agents looping through plan, implementation, pull request, review, and merge.
ZeroWeb
An experimental cross-platform Rust browser whose authors say almost all product and engine code is written by AI, with a human limited to design, decisions, and verification.
ForgeKernel
A self-evolving GPU-kernel agent from OpenBMB, with generated CuTe/CUDA kernels released in-tree and a paper reporting wins against expert libraries and other kernel agents.
KernelSeek
A question-driven CUDA kernel optimization agent that, according to its paper, produced dependency-free FlashAttention forward kernels faster than FA3 and FA4 on the authors' suites.
Machina
A modular RISC-V full-system emulator in Rust, presented as a human-and-agent collaboration using Claude and Codex.
Claude Fable 5.2 OS experiment
An Anthropic-announced experiment in which Claude Fable 5.2 coordinated more than 1,000 subagents over eight days to build a prototype operating system from an empty folder.
