px0 is a read-only web IDE designed for verifying code written by AI agents. It boots in under 1ms, uses 20MB of RAM (70x lighter than VS Code), and fuzzy-searches massive codebases like the Linux kernel in milliseconds—no config, no dependencies, just a single Go binary.

• Extreme performance: sub-millisecond startup, 6ms fuzzy search across 95,710 files, 20MB idle memory vs VS Code's 1,440MB across 15+ processes
• Purpose-built for verification workflows where agents write code and humans review it, not for typing—includes git awareness, diffs, symbol navigation, and optional LSP support
• Zero dependencies and distribution simplicity: single static binary with embedded HTML/CSS/JS, works on any box, no Node/Electron/plugins, spawns language servers on demand

Researchers tracked 112 professional developers using AI agents on the job and found they plan tasks, review every diff, and limit agent scope rather than handing off vague prompts. In trials, AI slowed senior devs by 19% and produced merged PRs only 8% of the time, revealing a 92% failure rate when agents ran unsupervised.

• Study of 112 pro developers found they treat AI agents like junior devs—scoping tasks tightly, reviewing every diff, and stepping in for cross-system or ambiguous work rather than vibe coding.
• In one trial, experienced open-source maintainers using AI were actually 19% slower.
• An agent connected to an issue tracker only got its PRs merged 8% of the time—a 92% failure rate when run with less supervision.
• The "hands-off swarm of agents" demos popular on social media don't match how real production code gets shipped.
