What is opencode-dash?

opencode-dash is a self-hosted dashboard that turns usage data from the opencode command line tool into visual charts and graphs. It reads a local SQLite database that opencode already creates on a user's machine, then shows sessions, token counts, costs, which AI models were used, and which coding agents were involved. To run it, someone installs the dependencies and runs a single command, which opens a dashboard in their web browser on localhost. The tool automatically detects whether it is running on macOS, Linux, or Windows and finds the opencode database in the right location without any manual configuration. Because everything runs locally, there is no backend server, no account to create, and no data ever leaves the user's device. The dashboard includes a calendar style heatmap of daily activity, a breakdown of which AI models were used most often shown as a pie chart, and detailed cost pages showing input, output, and reasoning token usage broken down by day, model, and provider. It is built on a tool called Evidence.dev, which turns SQL queries into a lightweight reporting website, and the final output can also be built as a static site and hosted anywhere. For anyone wanting to contribute, the README lays out the project's folder structure, the database tables opencode fills in automatically that the dashboard reads from, and step by step commands for setting up a local development copy, running tests, and building the project. The project is released under the ISC license, a short permissive license similar to MIT.
