Checkly is a serious tool for a specific kind of team. It runs Playwright-based synthetic monitoring — real browser checks and API checks with assertions — and its killer feature is that the same script runs in CI and as a synthetic monitor, which closes the gap between "passing in test" and "passing in production." If you write Playwright, want multi-step browser flows, and live in code, Checkly is genuinely hard to beat.
But a recurring question follows Checkly around: what does it cost at scale? Checkly bills per run. A single browser check running every 30 seconds from three regions generates 259,200 billable runs per month. A busy synthetic setup can produce surprise invoices, and there is no native on-call, no bundled status page, and SSO requires the Enterprise plan. When teams search for a Checkly alternative in 2026, it is usually because they want the reliability signal without per-run billing or the complexity of maintaining Playwright scripts in production.
This is not a hit piece on Checkly. It is excellent for code-defined synthetic monitoring. The question is when its scope stops fitting — when you need simple external uptime from multiple regions, a status page, and on-call, without per-run billing or a browser engine to keep alive.
Why Teams Look for a Checkly Alternative
The reasons cluster into a few themes.
Per-run billing
Checkly's pricing model is per execution. That is fine for a handful of checks, but it scales steeply: a 30-second browser check from three regions is a quarter of a million billable runs per month. A team that adds a few more checks, or shortens the interval, can watch the bill climb without changing what they monitor. Alternatives that price per monitor or flat make the cost predictable.
No native on-call
Checkly fires alerts; it does not schedule who is on call, escalate when someone does not acknowledge, or run an incident workflow. You bolt on a paging product for that, or you do without. Teams that need "alert person A first, then B after five minutes" usually outgrow Checkly at that point.
No bundled status page
Checkly focuses on the check, not the customer-facing surface. There is no built-in status page with a custom domain and subscriber notifications. When an incident happens, you need a separate page product to tell customers — another vendor, another bill.
Playwright complexity in production
Running Playwright in production is real engineering. Browser engines need patching, dependencies drift, headless modes break on the host, and a flaky script pages you on a synthetic failure that is not a real outage. Teams that just want to know "is my site up for users" often do not want to maintain a browser engine to find out.
SSO and enterprise features gated high
SSO requires the Enterprise plan. For teams with a security requirement that needs SSO below the top tier, the gating is a real blocker. Alternatives that offer SSO at lower tiers, or that do not need it because they are simpler, become attractive.
Authoring is developer-only
Checkly's authoring is code-first. There is no recorder for non-developers, and the monitoring-as-code workflow assumes a developer maintaining the scripts. For a team where monitoring is owned by ops or a non-developer, that is a mismatch.
None of this makes Checkly a bad tool. It is still the right pick for developer teams that want code-defined Playwright synthetic monitoring with CI/CD integration. A Checkly alternative is for teams that want simple external uptime, a status page, on-call, and predictable pricing — without maintaining a browser engine in production.
What to Look For in a Checkly Alternative
1. Pricing model
- Per-run, per-monitor, or flat?
- How does cost scale as you add checks or shortens intervals?
- Are there overage fees or hard caps?
The biggest reason to switch off Checkly is per-run billing. Make sure the alternative prices in a way that does not surprise you.
2. Check types and simplicity
- HTTP/HTTPS, TCP, ping, DNS — built in and simple to add?
- Do you need a real browser engine (Playwright), or are simple external checks enough?
- SSL certificate expiration, keyword and content checks included?
If you do not need multi-step browser flows, a simpler tool avoids the Playwright maintenance burden.
3. Status pages
- Is there a public status page with a custom domain?
- Can customers subscribe for incident notifications (email, SMS, Slack, webhooks)?
- Is there incident communication tooling for updates during an outage?
4. On-call and alerting
- Native on-call rotations and escalation, or do you wire up a separate pager?
- Modern alert channels — Slack, Discord, SMS, Microsoft Teams, webhooks?
- Smart alerting that reduces noise and avoids alert fatigue?
5. API and automation
- Can you manage monitors programmatically (REST API, Terraform, IaC)?
- Can you integrate with CI/CD for ephemeral environments?
6. Free tier
- Is there a free plan to start, or only paid tiers?
- Does the free tier cover meaningful usage, or is it a teaser?
Checkly vs Simpler Uptime Monitoring
| Dimension | Checkly | Simpler uptime monitoring |
|---|---|---|
| Engine | Playwright (real browser) | HTTP/TCP/ping (no browser) |
| Pricing model | Per-run (billable executions) | Per-monitor or flat |
| Check focus | Multi-step browser + API synthetic | External uptime, SSL, DNS |
| Status page | None (separate product) | Built-in, custom domain, subscribers |
| On-call / escalation | None (separate pager) | Built-in rotations + escalation |
| Alert channels | Email, Slack, webhooks | Slack, Discord, SMS, Teams, webhooks |
| Authoring | Code-first (Playwright) | UI + API, add a monitor in seconds |
| SSO | Enterprise plan | Varies — check the tier |
| Setup time | Minutes (with scripts) | Minutes (no scripts) |
| Cost at scale | Climbs with frequency × regions | Predictable, per-monitor |
| Best for | Code-defined synthetic + CI/CD | External uptime + status + on-call |
The table is not "Checkly bad, simpler good." It is "different jobs." If you write Playwright and want the same script in CI and production, Checkly is excellent. If you want to know whether your site is up for users from multiple regions, with a status page and on-call, and without per-run billing, the simpler column is the better fit.
How Webalert Compares as a Checkly Alternative
Webalert is a hosted, multi-region uptime monitor — the simpler external layer Checkly does not focus on.
- No per-run billing — Webalert prices per monitor, not per execution. A 30-second check from multiple regions is one monitor, not a quarter-million billable runs.
- No browser engine to maintain — HTTP, HTTPS, TCP, and ping checks from multiple regions, without a Playwright runtime to patch or a headless browser to keep alive.
- Native check types — SSL certificate expiration, DNS, domain expiry, keyword and content checks, and authenticated endpoints (bearer tokens, custom headers) supported out of the box.
- Public status pages — a customer-facing surface with custom domain and subscriber notifications, the thing Checkly lacks entirely.
- Incident management — on-call, escalation, and post-incident review in one place, instead of a separate paging product.
- Smart alerting — downtime confirmed from multiple regions before paging, which directly attacks the alert fatigue that noisy synthetic checks can create.
- Heartbeat monitoring — for cron jobs and scheduled tasks that should phone home, catching the silent failures active checks miss.
- Free tier — start monitoring without a browser engine, a credit card, or a Playwright script.
The honest framing: if you depend on multi-step browser flows or Playwright-in-CI parity, Checkly is the right tool and you should keep it. For simple external uptime from multiple regions, with status pages and on-call, and predictable pricing, the move is straightforward.
How to Migrate Off Checkly
1. Inventory your checks
Export every Checkly check: name, URL, type (browser/API), assertions, frequency, regions, and notification settings. Tag each as "external uptime" or "multi-step synthetic." The first group moves to a simpler uptime monitor; the second may belong in Checkly or a dedicated synthetic tool.
2. Map the external-uptime checks
For each external-uptime check, create the equivalent monitor (HTTP, TCP, DNS, SSL) in the new tool. Set check frequency and alert thresholds. Configure alert channels and on-call routing to match your current behavior.
3. Run in parallel
Run Checkly and the new monitor side by side for one to two weeks. Compare alert timing and accuracy. If the new tool fires earlier (multi-region) or more accurately (confirmed downtime), you have your evidence. If it misses something, add it before cutover.
4. Cut over the external-uptime layer
Once parity is confirmed, switch the external-uptime alert routing to the new tool and silence those checks in Checkly. Keep Checkly running for the multi-step browser synthetic checks it does best.
5. Decide on the multi-step synthetic checks
For the multi-step browser flows that did not map cleanly, decide case by case: keep them in Checkly, move to a dedicated synthetic tool, or accept the risk. Most teams find the bulk of what they thought they needed was actually simple external uptime in disguise.
Frequently Asked Questions
Is Checkly still worth using in 2026?
Yes, for developer teams that want code-defined Playwright synthetic monitoring with CI/CD integration. For teams that need simple external uptime, a status page, and on-call, without per-run billing, a simpler alternative is usually a better fit — and the two can run together.
What is the best Checkly alternative?
It depends on your needs. If you want simple external uptime with status pages and on-call, look for a tool that bundles those natively and prices per monitor, not per run. Webalert is one option; the comparison table above covers what to evaluate.
Does a Checkly alternative replace Playwright monitoring?
For simple external uptime, usually yes. For multi-step browser flows and Playwright-in-CI parity, Checkly or a dedicated synthetic tool is still the right fit. The two serve different parts of the monitoring stack.
What about Checkly's per-run billing?
Per-run billing is the main reason teams switch. A 30-second browser check from three regions is roughly 259,200 billable runs per month. A per-monitor or flat-priced alternative makes the cost predictable without changing what you monitor.
Can I run Checkly and a simpler monitor together?
Yes, and many teams do. A common hybrid is a simpler uptime monitor for external, multi-region checks and status pages, and Checkly for the multi-step browser synthetic flows it does best. That is a legitimate end state.
Get the Reliability Signal Without Per-Run Billing
If your monitoring is priced per execution and you are maintaining a browser engine to get an up/down signal, the simplest cost cut available is to add a simpler, multi-region uptime monitor that ships status pages and on-call in the same product.
Start monitoring from multiple regions — free. No per-run billing, no Playwright runtime, no browser engine to maintain. Webalert checks your endpoints from outside your network and pages the right person when your users stop reaching you — so you can keep Checkly for the multi-step flows and hand the external uptime job to a tool built for it.
