Checkly checklyhq.comCan AI replace Checkly?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Checkly, run scheduled API and browser checks from one independent worker. The hard boundary is global browser fleet, playwright operations, alerting, ci integration, and support, plus independent infrastructure and reliable alerting.
Replacing a paid app means you set it up and keep it running: hosting, updates and backups can be on you. What you give up.

Checked Aug 14, 2026 · source: checklyhq.com.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Hobby | Free | Free | 1 user; 10 uptime monitors; 2-minute minimum interval; 1,000 browser/Playwright runs; 10,000 API runs; 7-day raw retention |
| Starter | — | $24/mo | 3 users; 50 uptime monitors; 1-minute interval; 3,000 browser runs; 25,000 API runs; 100 SMS alerts; 7-day raw retention |
| Team | — | $64/mo | 10 users; 75 uptime monitors; 30-second interval; 12,000 browser runs; 100,000 API runs; 200 SMS + 200 phone alerts; 30-day raw retention |
| Enterprise | — | — | Custom users and monitor volumes; 1-second scheduling available; 180-day raw and 25-month aggregate retention |
Hidden costs: Starter/Team charge $8 per extra block of 25 uptime monitors; browser overages are $6.50/$6.25 per 1,000 and API overages $2.60/$2.50 per 10,000; every parallel location and retry counts, and each 30 seconds of a Playwright suite consumes 1 run
02Could AI build it for you?
The core job: Run scheduled API and browser checks from one independent worker, receive bounded error or log events, alert through one channel, and publish an honest status page.
What a working version needs:
- server outside the monitored failure domain
- PostgreSQL
- optional ClickHouse
- email or webhook destination
- public HTTPS
Editorial comparison targets the Starter plan and a small independent monitoring service DIY substitute. Recheck price before merge.
03What you'd give up
- global browser fleet, Playwright operations, alerting, CI integration, and support
- global probe network
- phone and SMS delivery
- massive retention
- advanced incident response and support
People still pay for Checkly because monitoring must continue working during the exact outage it reports, which makes independent infrastructure and alert delivery the real product. The recurring cost buys probe geography, clocks, retries, deduplication, sampling, storage, paging, notification delivery, on-call rules, and its own uptime, not just the visible interface.
