Cap is the open source alternative to Loom. It's a video messaging tool that allows you to record, edit and share videos in seconds.

Cap Web is available to self-host using Docker or Railway, see ourself-hosting docs to learn more.You can also use the button below to deploy Cap Web to Railway:

Cap Desktop can connect to your self-hosted Cap Web instance regardless of if you build it yourself ordownload from our website.

We use a combination of Rust, React (Next.js), TypeScript, Tauri, Drizzle (ORM), MySQL, TailwindCSS throughout this Turborepo powered monorepo.

A note about database: The codebase is currently designed to work with MySQL only. MariaDB or other compatible databases might partially work but are not officially supported.

• desktop: ATauri (Rust) app, usingSolidStart on the frontend.
• web: ANext.js web app.

• ui: AReact Shared component library.
• utils: AReact Shared utility library.
• tsconfig: Sharedtsconfig configurations used throughout the monorepo.

Cap usesTinybird to ingest viewer telemetry for dashboards. The Tinybird admin token (TINYBIRD_ADMIN_TOKEN orTINYBIRD_TOKEN) must be available in your environment. Once the token is present you can:

• Provision the required data sources and materialized views viapnpm analytics:setup. This command installs the Tinybird CLI (if needed), runstb login when a.tinyb credential file is missing, copies that credential intoscripts/analytics/tinybird, and finally executestb deploy --allow-destructive-operations --wait from that directory.It synchronizes the Tinybird workspace to the resources defined inscripts/analytics/tinybird, removing any other datasources/pipes in that workspace.
• Validate that the schema and materialized views match what the app expects viapnpm analytics:check.

Both commands target the workspace pointed to byTINYBIRD_HOST (defaults tohttps://api.tinybird.co). Make sure you are comfortable with the destructive nature of the deploy step before runninganalytics:setup.
