Deploy your Slack app
straight from the chat.
Ask Claude Code, Cursor, Codex or any MCP editor to deploy and it stays connected from then on. Nothing to expose to the internet, and nothing to keep warm.
Free for 7 days, then $3/mo. No card to start.
ONE COMMAND · ALWAYS CONNECTED · NOTHING EXPOSEDNow it is there
every morning.
The websocket stays open because the process never stops, so the reminder fires on Monday whether or not anyone is at a desk. Crashes restart on their own.
One command from your editor. No build config to write.
The xoxb- token from your app, plus SLACK_APP_TOKEN if you use Socket Mode. Both encrypted.
The socket is held open. If the process dies it restarts; if the machine dies it moves.
The bit you are
actually wondering.
Do I need to expose an endpoint or set up ngrok?
No. Your app connects outward to Slack, so nothing needs to reach it from the internet. That is why this shape fits here.
Will a Bolt app fit on the cheapest plan?
Comfortably. We measure a Bolt app at roughly 85MB running, and the smallest plan gives it 512MB.
What about the Events API instead?
That one does need a public address. Talk to us and we will sort it, but the connect-outward approach is simpler and almost certainly what your app already uses.
Whatever it built,
this runs it.
Your app holds an open connection to Slack and receives events down it, so nothing has to reach you from outside. That needs a process that stays connected, which is the whole point of this.
You never open a panel.
Connect once, then deploy, read logs, restart and roll back by asking. No API key to copy.
Priced per app,
not per request.
No metering, no surprise invoice. Seven days free to start, and no card until you keep it.
SOLO for slack apps. A Slack app holds one connection and little else. We measure a typical one at about 85MB running.
What people ask
before they deploy.
Does my app need a public web address?
No. The usual setup has your app connect outward to Slack, so nothing has to reach it from the internet — and it is what an app built with an AI assistant almost always uses. If yours receives events at a public URL instead, talk to us.
Which tokens do I need?
SLACK_BOT_TOKEN (starts xoxb-) always. SLACK_APP_TOKEN (starts xapp-) as well if you use Socket Mode. Both from api.slack.com → your app → OAuth & Permissions and Basic Information.
Will it fit on the cheapest plan?
Comfortably. We measure a Bolt app at about 85MB running; Solo gives it 512MB.
