Position
What you can expect
Tools for developers and agile teams who would rather ship than set things up. This is how we build them, and what that means for you.
01
Easy to start, deep when you need it
Sensible defaults get you a working schedule or monitor in about a minute. When you need more, the controls are there: intervals, headers, payloads, retries, grace periods. A simple first screen does not mean a shallow tool.
02
AI where it helps
Describe what you want in plain language and get a working workflow back. Plug the tools into Claude Code, Codex or any other MCP client and run them from where you already work.
03
One account, every tool
Sign in once. Every tool that needs an account uses the same one, with the same billing and the same team. The ones that do not need an account stay that way.
04
Alerts where you already are
Slack, Discord, Telegram, email, or a webhook to anything else. You choose where a failure shows up. Nobody should have to remember to open a dashboard.
05
We run on it too
Our own jobs, checks and deploys go through these tools. When something breaks we are usually the first to know, and the fix is our problem before it is yours.
Built in Copenhagen. Used every day by the people who make it.
All three live in one Crontap account, with one notification list and one dashboard. Each catches a kind of failure the other two miss.
CRNThe flagship
Crontap
Schedule recurring API calls with cron syntax.
Crontap calls your endpoints on a schedule you write in cron or plain English. Pick a frequency and a timezone, test the call once, and forget about it.
Cron expressions, or plain English like โevery weekday at 09:00โ
A timezone per schedule, so daylight saving does not move your jobs
Test the call before you save it. Re-run it any time after.
Custom method, headers and body for each scheduled request
Point Crontap at a public URL and it checks it on an interval, from every minute to once a day. You get 90 days of history, daily uptime bars, and an email when it stops responding.
Probe any HTTP or HTTPS URL with an anonymous GET request
Nine interval options, from every minute to every 24 hours
A 200โ399 response counts as up. Timeouts and network errors count as down.
Set the failure threshold: 1 to 5 consecutive failures before a monitor is marked down
Clobbr hits an endpoint in sequence or in parallel and shows what happens to response times under load. It runs on your machine, on macOS, Windows or the CLI. One lifetime licence, no account.
Page AI plans, designs and writes your website, then hands you clean code instead of locking you into an editor. It does the first draft. You finish it.
Read, debug and compare cron expressions on a calendar.
Paste a cron expression and see exactly when it fires. CronTool puts several schedules side by side on one calendar, understands extended syntax, and needs no account.
Crontap is free to start and takes about a minute to set up. It catches the call that failed, the URL that stopped answering, and the job that never ran.
