Running the binary directly

Getting the binary

You can either build from source or use the precompiled binaries. You can download the latest precompiled binary release from Releases. If your platform is not supported, leave us a GitHub issue. In the meantime, you can build from source.

Note: On MacOS you might need to hold the option key and double click the binary file in Finder once, to circumvent the Gatekeeper warning.

Generate a new instance secret

Instance secret is the secret to the backend. Keep very safe and only accessible from the backend itself. Generate a new random instance secret with

cargo run -p keybroker --bin generate_secret

It will look like this: 4361726e697461732c206c69746572616c6c79206d65616e696e6720226c6974

Generate a new admin key

With the instance name and instance secret, generate an admin key. Admin key is required to push code to the backend and take other administrator operations.

cargo run -p keybroker --bin generate_key -- convex-self-hosted 4361726e697461732c206c69746572616c6c79206d65616e696e6720226c6974

Run your backend instance

Adjust the path based on where you downloaded the binary to or add it to your PATH. The backend will store its database in the current-working-directory (not where the binary file lives).

Use the instance name and instance secret to start your backend.

./convex-local-backend --instance-name convex-self-hosted --instance-secret 4361726e697461732c206c69746572616c6c79206d65616e696e6720226c6974

To run with Postgres, add --db postgres-v5 <connection string> to the command, being sure to strip out the database name and query parameters. See Postgres instructions. To run with MySQL, add --db mysql-v5 <connection string> to the command and similarly strip out the database name and query parameters.

You can run ./convex-local-backend --help to see other options for things like changing ports, convex origin url, convex site url, local storage directories and other configuration.
