FAQ
What exactly happens after I pay?
Complete checkout → go to /activate with the same email → receive your dg_ API key → register watches via API or MCP. See Product for endpoints.
Why is Team $99 instead of Pro?
Team adds 4× watches, 6× faster checks, 2×+ retention, and 10× export capacity. Read the Team breakdown for scenario math and Pro vs Team comparison.
Can I self-host instead?
Yes — the diff engine and MCP client are MIT-licensed on GitHub. Hosted adds continuous cron, history, webhooks, and billing-backed API keys.
Founding member pricing?
First 50 Pro customers lock in $29/mo forever (list $39). Team is not discounted at launch.
