Fast Rust LGS
A drop-in RGS server on your machine. It reads your math files straight from disk and answers wallet calls in microseconds.
Open-source workbench · Stake Engine RGS
Ship slots with a real dev loop.
Stake Dev Tool runs your game against a fast Rust RGS on your machine. Test it at every resolution side by side, replay any round, and hand your team a link that just plays.

Everything the RGS contract needs.
Multi-resolution test view
The same game at seven resolutions side by side, each frame its own session. QA sees exactly what players will.
Real share links
Hand anyone a URL on its own subdomain. They play against a real server-side RGS, and your math never leaves the server.
crates/server
One engine, three surfaces.
The same Rust engine that powers your local loop also runs in the cloud: a web workbench for your team, and real hosted game instances behind every share link. Zero install for math devs, QA and PMs.
