Type /leppa #release-foo and Leppa gives the channel a seven-day half-life. It auto-archives unless someone extends it — so your sidebar stays the channels you actually use.
Free while in beta · No message content stored
Three steps, no maintenance.
One install for the whole workspace. No per-channel setup, no bots to babysit.
Leppa spins the channel up and starts a seven-day half-life the moment it's created.
A day out, Leppa warns the channel. Hit Extend to reset the clock — or let it tidy up.
Active, warned, archived — the same three states you’ll see across Leppa.
Fresh channel, plenty of runway. The half-life meter ticks down quietly in the background.
Twenty-four hours left. Anyone can press Extend to keep it, or just let it wind down.
Archived, not deleted. History stays searchable in Slack — the sidebar just gets its space back.
Still shipping? Reset the clock from the warning message or the dashboard. No admin ticket required.
Every tenant is query-scoped and its Slack token is encrypted at rest with a key derived per workspace.
Leppa keeps Slack IDs and a hashed workspace name — never emails, names, or anything you've typed.
Cloudflare Workers, D1 and Durable Objects. Timers fire reliably without a server to keep warm.
Install Leppa in under a minute and never archive a stale channel by hand again.
