Enterprise tools weren't built for you
Most monitoring tools are designed for DevOps teams with dedicated budgets. They cost hundreds per month and take days to configure. You just want to know if something broke.

AI Summary
Your app's average response time climbed to
284ms this week — up from 196ms last week.
The culprit is almost certainly
Thursday's 2:40 PM deploy, which introduced
two N+1 query patterns on
/api/users/:id/posts
and
/api/feed. P95 latency on those endpoints is now sitting at 1.2s.
The good news: your error rate held steady at 0.4% and overall
request volume was up 12% — growth without breakage.
Action recommended: add
select()
eager-loading to the two flagged endpoints before they start
affecting retention.
You're flying blind.
Raw metrics don't tell the whole story
Graphs show you what happened. They don't tell you why it happened, which deploy caused it, or what to actually do about it.
You find out too late
By the time a user reports a slowdown, it's already been hurting your app for hours. You need something watching while you're not.

Questions?
Currently Node.js and Express. Next.js, Django, Rails, and
Laravel support is coming soon.
No. The SDK is async and non-blocking. If our ingestion API is
unreachable, your app keeps running normally — we just miss
some data points.
If you've added a payment method, your plan starts
automatically on day 8. If not, your account is paused and
your data is retained for 30 days.
Yes. Cancel before day 8 and you won't be charged at all.
Cancel after and you keep access until the end of your billing
period.
Those tools are built for DevOps teams at companies with
dedicated infrastructure budgets. PulseChek is built for
developers who just want to know if something is wrong —
without a week of setup or a $500 monthly bill.
Yes. All data is encrypted in transit and at rest. We store
only performance metrics — no request bodies, no user data, no
PII.
