Sub-millisecond GPU presentation

Glyphs are cached directly into a high-throughput GPU texture atlas. Frame presentation stays under 0.4 ms even when subagents generate thousands of lines of streaming output.

ConPTY pane multiplexing

Run Claude Code, Antigravity subagents, and test watchers simultaneously side-by-side. Pexer multiplexes multiple pseudo-consoles without window clutter or heavy terminal multiplexers.

Zero Electron, zero analytics

Built with pure native C. A tiny 2.49 MB executable that launches in under 12 ms, uses 28 MB baseline RAM, and never makes background network calls.

Active Developer Community

Discuss agent workflows, report issues, share performance benchmarks, and test nightly builds directly with the creators.
