ShiftGuard
ShiftGuard watches your APIs for silent schema, field, or limit changes and pings you before your users notice.
How it works
Connect an API — pick Stripe, OpenAI, Notion, etc.
ShiftGuard monitors — diffs docs/specs & runs lightweight probes.
Get alerted early — Slack/Discord/Email/Webhook when something changes.
Features
Prevent downtime — know about breaking changes before prod incidents.
Save engineering hours — skip brittle contract tests & DIY scripts.
Smart alerts — only pings for meaningful diffs (removed/renamed fields, auth/rate-limit changes, deprecations).
What developers told us
“We only notice when error rates spike.”
“Downtime was $10k/min at my last company.”
“Not all users complain — most just leave.”

FAQ
Is this a replacement for logging/APM?
No. ShiftGuard is proactive change detection. Keep your logging/monitoring; we prevent surprises.
How do you detect changes?
Spec/doc diffs + live probes + heuristics for breaking vs. harmless changes.
What about false positives?
Nobody wants spammy alerts. We only flag meaningful diffs (removed fields, auth, limits). You can mute noisy endpoints.
Which APIs are supported first?
We’re starting with Stripe, OpenAI, and Notion. Vote your API when you sign up.
When can I use it?
Early access rolling out as we add APIs. Join the list to get in.
