A free, open-source alternative to Signalyst. They charge $250/mo.
Free
Signal Desk
Product alerts routed from your own warehouse to Slack, on rules written as SQL.
Teardown
3 parts, wired together
- 01DuckDBTODO — runs the rule queries against your exported events.
- 02Cron triggersTODO — evaluate every rule on a schedule you set.
- 03Slack incoming webhooksTODO — deliver the alert to the channel.
What it does
TODO — replace this placeholder description.
Signal Desk covers the one job Signalyst charges $250/mo for, and stops there. It runs on your own machine or your own hosting, against your own key, so the running cost is whatever the underlying API charges and nothing on top.
TODO — describe the actual loop the tool handles here.
Run it yourself
Bring your own API key. Three commands from clone to running.
$ git clone https://github.com/rebuiltlabs/signal-desk.git$ cd signal-desk && npm install$ cp .env.example .env # add your own API keyWhat I cut
Where it stops short of Signalyst
- TODO — no visual rule builder; rules are SQL files.
- TODO — no anomaly detection, only thresholds you write.
- TODO — Slack only — no PagerDuty or SMS routing.
