Status
High-voltage beta
Expect breaking changes, missing std symbols, and compiler panics.
Before you dive in
- The Zig toolchain boots entirely in-browser using an experimental WASM build that still misses upstream optimizations.
- Compiler crashes, stack overflows, or hanging workers are known issues—refreshing typically clears the slate.
- Runtime assets download on demand. Slow or flaky networks may cause warmups to fail the first time around.
- Output, logs, and editor state are ephemeral. Export the generated WASM if you need a durable artifact.

What to do
Refresh responsibly
Keep exports handy and share repros via GitHub issues when things explode.

Sessions reset on refresh. Export the compiled WASM if you need to keep work between visits.
