# okokumo > okokumo monitors HTTP(S) endpoints, cron jobs and heartbeats, SSL/TLS certificate > expiry and domain expiry. Data is hosted in France (Scaleway, fr-par); probes run in > two EU regions. An HTTP, TLS or domain check failure is confirmed from a second, > independent EU probe region before alerting; alerts go out by email, Telegram, Slack, > Discord or an HMAC-signed webhook. English is the canonical language of this site. Most product pages also exist in French, German, Dutch, Italian, Spanish and Portuguese under /fr/, /de/, /nl/, /it/, /es/ and /pt/. The Free plan has 5 checks and needs no card. ## Free tools No account, and nothing you type is stored. The TLS and domain checkers run the same check the paid monitoring runs; the cron tester runs entirely in your browser. - [Free SSL/TLS certificate checker](https://okokumo.com/tls-checker): Check any domain's SSL/TLS certificate in one click — expiry date, days remaining, issuer, chain validity and handshake time. No account, nothing stored, run from France. - [Cron expression tester](https://okokumo.com/cron-expression-tester): Paste a cron expression and see what it means in plain English — which fields are which, the next 8 run times in your time zone, the day-of-month/day-of-week trap, and how it behaves across a daylight-saving change. - [Free domain expiry checker](https://okokumo.com/domain-expiry-checker): Check when a domain registration expires and whether it still resolves — expiry date, days remaining, registrar and DNS status for any public domain. No account, nothing stored, run from France. - [All free tools](https://okokumo.com/tools) ## Product - [HTTP monitoring](https://okokumo.com/http-monitoring): Monitor any HTTP(S) endpoint from two EU regions, on an interval from 30 seconds to 24 hours, with assertions on status code, latency, body and headers. Hosted in France. - [Cron job monitoring](https://okokumo.com/cron-job-monitoring): Heartbeat monitoring for scheduled jobs: your job pings a unique URL after each run, and silence past its deadline is a failure. Understands crontab expressions and the timezone your server runs them in. - [SSL certificate and domain monitoring](https://okokumo.com/ssl-certificate-monitoring): Certificate expiry alerts at 30, 14, 7 and 1 days out, invalid-chain detection and SNI support, plus domain registration expiry and DNS resolution failures. Hosted in France. - [Alerting](https://okokumo.com/alerting): Email, Telegram, Slack, Discord and HMAC-signed webhooks, routed per check, deduplicated so a down service pages you once, with a delivery log showing what was sent and what was deliberately skipped. - [Tower — public status pages](https://okokumo.com/tower): Tower: a public status page for your services, fed directly by okokumo's monitoring probes. Available on Pro and Business. ## MCP server - [MCP server — okokumo in Claude, ChatGPT, Cursor and VS Code](https://okokumo.com/mcp): okokumo's hosted MCP server lets Claude, ChatGPT, Cursor, VS Code or any MCP client read your checks, create and pause them, and write status-page incidents.
