One of 74 tools in Coding
Who it's for
- Developers who want an AI coding workflow in the terminal for inspecting files, editing code, and running tests.
- Developers who want to start a coding task in the terminal and continue steering or reviewing it from a phone or web interface.
- Developers who want Praex-hosted models or the option to bring their own keys or hardware.
How it fits your workflow
Install the CLI, then use Praex in the terminal or chat. The page's example has Praex read a build configuration, run tests, edit a source file, and check that the tests pass.
A task can be started in the terminal, steered from a phone, and reviewed on the web. Praex says the same agent, memory, and session carry across those screens.
