Quickstart
Sleev is a context-management gateway for AI coding agents, bundled with a
small command-line tool, sleev, that
installs and manages it. Both run entirely on your own machine, so your data
stays local and private. Sleev sits transparently between your harness and
your model provider, and it never changes how you use your harness.
Harnesses resend their entire conversation on every turn, which burns tokens quickly as a session grows. Sleev intelligently manages that history by compressing the stale parts into compact summaries while keeping recent and relevant context and your provider's prompt cache intact, so you send far fewer tokens upstream and save a significant amount on usage.
Install
Start by installing the sleev
command-line tool, which you use to set up and manage the gateway. On macOS and
Linux, the easiest way is the install script, which downloads
sleev and adds it to your path.
If you prefer npm, you can install
sleev with npm instead, which works on
macOS, Linux, and Windows:
Setup
With sleev installed, run it to open the
TUI.
Sign in
The first time you run sleev, it
asks you to sign in to your account. This links the gateway on your machine to
your Sleev account so your usage and metrics show up in your dashboard.
Command-line setup
If you want to use only the CLI, run each step from the terminal.
Sign in to your Sleev account:
Register this machine and start the local gateway:
Check the gateway
After setup, confirm the gateway is running locally:
Stay up to date
Each time you open sleev, it checks
for a newer release. If one is available, a notification appears in the corner
with the new version and an Update button that upgrades the CLI and the
gateway in one step.
Or update from the command line at any time:
If you want to pin a version, do so like this:
