Install or open RLViz
Start in the browser
Open https://rlviz.dev. The viewer loads four reviewed public Terminal-Bench trajectories: reward-0 and reward-1 runs for two tasks. Use Settings to open another local trace or reviewed .rlviz bundle, choose a clearly labeled synthetic example, change theme, or load a reviewed browser adapter.
Supported files are parsed in memory in the current tab. No account or upload is involved.
Install the local CLI
Homebrew:
brew install TheSnakeFang/tap/rlviz
npm:
npm install --global rlviz
Verified shell installer:
curl -fsSL https://rlviz.dev/install.sh | sh
Then run the setup wizard and open a trace:
rlviz init
rlviz inspect ./path/to/trace.ndjson
rlviz open ./path/to/trace.ndjson
rlviz with no arguments restores the last usable source. With no history it opens the bundled synthetic gallery.
Let a coding agent operate the workspace
Install the RLViz instructions during rlviz init, or run rlviz setup agent. The agent can query canonical trajectories, choose IDs, open a named GUI workspace, and update that open workspace without browser automation.
