Developer Tools / AI/ML Performance Testing

HEADROOM

A 30-second WebGPU benchmark that measures a device’s memory-bandwidth ceiling for local AI and checks for a WebGPU subgroup correctness bug, with receipts, projections, and comparison data.

Why it was accepted

The page is clearly an AI-adjacent developer tool with a concrete purpose: benchmarking GPU bandwidth and estimating local-LLM throughput. The crawl shows the tool’s workflow, outputs, methodology, receipts, and example comparisons across devices and engines, which is enough evidence for a useful public listing. It also has a distinct angle beyond a generic benchmark by pairing performance measurements with a WebGPU canary for a correctness bug.

Weakness

The snapshot does not show a simple quick-start, API, or install path for builders who want to integrate it elsewhere. It also doesn’t make the underlying code/repo status, release cadence, or browser/device support boundaries fully explicit beyond the visible WebGPU and Chrome-related notes.

Developer Tools / AI for Code

CodeGraph is a local code knowledge graph for AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Hermes Agent. It aims to cut token use, tool calls, and runtime by letting agents query pre-indexed code structure instead of scanning files repeatedly.

Developer Tools / AI Agents

Single-binary CLI that builds an AI agent knowledge base from git repos, Claude Code/Codex sessions, and saved links. It generates a portable markdown wiki, runs on cron, supports local Ollama mode, and exposes the result for agents via CLAUDE.md/AGENTS.md and MCP.
