The gap
A green homepage is not a healthy stack.
Your homepage can be green while the database behind it refuses every connection. The 4am pages usually don't have a public URL — CuliPulse watches those too.
How it works
Two ways in, one dashboard.
Paste a URL and we check it from our shared locations in Singapore, Frankfurt and Montreal — from outside your network, so you see what your users see, including problems your own network never reveals. They can only reach public addresses: for a private host, use your own agent.
One static Go binary on a box inside your network runs the same checks and streams results out over an outbound 443 connection. No inbound ports, no VPN. Turn on auto-discovery and it suggests monitors for what it can reach — you approve what matters.

Checks
Nine check types. Dozens of presets.
Every check runs from our shared agents or your own private agent — same alerting rules either way (private hosts need your own agent). Even the third-party vendors you depend on, watched from their own status page and pinned to the monitors that rely on them.
Vendor & dependencies
Know when it's your vendor, not you.
Half your 3am pages aren't your fault — an auth provider, a payment API, a cloud region. CuliPulse watches your vendors' own status and pins it to the monitors that depend on them, so when you open a red monitor you can already see whether one of its dependencies is having a bad day too.
A vendor's own status page — Anthropic, AWS by service & region, Cloudflare, GitHub and more — turned into a monitor you can alert on.
Pin the vendors a monitor leans on; their live status shows right on that monitor's page and rolls up into one line.
You see your monitor's state and each dependency's status side by side. CuliPulse doesn't claim the vendor caused it — the judgment stays yours.
Status & reports
Prove your uptime.
Turn any set of monitors into a shareable SLA report or public status page — no login for the people you send it to.
Every credential, header and payload you store is encrypted at rest with authenticated encryption.
The agent dials out over 443. You never open a port or hand us network access.
Each agent gets its own key, scoped to its own checks and revocable on its own.
Pricing
Every monitor type on every plan.
Built on Cloudflare, so the free tier stays free. Paid plans buy volume, faster checks, more locations and longer history.
