Website Health Checks in CI/CD

Running website health checks in CI/CD pipelines helps you validate deployments, detect issues early, and maintain site reliability. Instead of discovering issues after deployments reach production, you can detect issues before they affect users.

Health checks are a critical part of the CI/CD workflow. They help teams validate that deployments do not break anything, detect issues before they reach production, and maintain site reliability.

This guide shows you how to run website health checks in CI/CD, with step-by-step workflows and integration patterns.

Add health check steps to your CI/CD pipeline. Run checks before deployment to ensure the site is healthy, and after deployment to validate that the deployment did not break anything.

Use the MonitorMojo API or CLI to run checks. The API returns structured JSON data that is easy to parse and analyze. The CLI provides a simple interface for running checks and retrieving results.

If checks fail, fail the pipeline. This prevents broken deployments from reaching production. The pipeline should provide clear error messages so the team can quickly identify and fix the issue.

You can run checks at multiple stages: before deployment, after deployment, and on a schedule. The more comprehensive the checks, the more confident you can be that the site is healthy.

Before deployment, run health checks to ensure the site is healthy and ready for deployment. If checks fail, do not proceed with the deployment.

After deployment, run health checks to validate that the deployment did not break anything. Compare the results to the pre-deployment checks to identify any changes.

If post-deployment checks fail, roll back the deployment or fix the issue immediately. The CI/CD pipeline should alert the team immediately so they can investigate and resolve the issue.

MonitorMojo provides historical data, so you can compare pre-deployment and post-deployment results to identify any changes. This helps you understand the impact of deployments.

Not running checks before deployments is a common mistake. If you do not check the site before deployment, you might deploy a broken site.

Not running checks after deployments is another mistake. If you do not check the site after deployment, you might not detect issues until users report them.

Not failing the pipeline when checks fail is a third mistake. If the pipeline continues even when checks fail, broken deployments can reach production.

Not providing clear error messages is a fourth mistake. If the pipeline does not provide clear error messages, the team cannot quickly identify and fix the issue.

MonitorMojo provides an API and CLI that make it easy to run health checks in CI/CD pipelines. The API returns structured JSON data that is easy to parse and analyze.

The API is designed for CI/CD integration. It provides clear endpoints, structured responses, and comprehensive documentation. Your CI/CD pipeline can run checks, retrieve results, and fail the pipeline if issues are detected.

MonitorMojo also provides historical data, so you can compare pre-deployment and post-deployment results to identify any changes.

The credit-based pricing means you only pay for the checks you run. No per-site monthly fees. This makes it easy to scale your monitoring without breaking the budget.

Website Health Checks in CI/CD is best understood as a repeatable website health workflow, not a promise that every outage or configuration issue will be avoided. Learn how to run website health checks in CI/CD pipelines, validate deployments, and maintain site reliability with automated health checks.

In practice, this workflow centers on uptime, SSL certificates, response time, security headers, website health summaries, and monthly review notes. Each check is planning input: it can show that the production site is reachable, that a certificate has a given expiry window, that response time has shifted, or that a header is missing. It cannot prove root cause by itself or replace a human response. The value is in making the review consistent enough that developers and DevOps teams can spot issues before someone downstream has to ask about them.

Beyond that primary audience, the same checks are reusable by anyone with a public-facing URL that matters to revenue, leads, or reputation: a recurring review is cheap insurance compared to hearing about the problem from a client or customer first.

Start by listing the URLs that actually matter instead of just the homepage — for a developer confirming production is healthy right after a deployment, that usually means the pages tied to revenue, signups, or trust, not every page on the site.

Next, define the check types for each URL: reachability, HTTP status, HTTPS/SSL certificate status and expiry window, response time, redirect behavior, and security header presence. For API, CLI, and AI-agent workflows, document which endpoint or command runs the check and where the result is stored.

Set a cadence that matches the risk — a low-traffic page may only need a monthly look, while a page tied to revenue or signups deserves a check after every deployment and before any campaign or launch.

Record what you find with a consistent format: URL, check type, status, issue, owner, detected date, and next review date. Then say what actually happened in plain language — a check can surface a symptom, but developers and DevOps teams still need to confirm the cause.

• Choose the URLs that matter most to visitors, clients, revenue, and operations.
• Run uptime, SSL, response time, and security header checks on a consistent schedule.
• Triage failed or risky checks by likely owner: hosting, DNS, SSL, code, platform, or third party.
• Record notes in a repeatable format so future reviews do not start from scratch.
• Send a plain-language summary with the issue, impact, owner, and next review date.
• Run a confirmation check after remediation so there is an external result to reference.

Use this template for recurring reviews: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Resolved Date], [Next Review Date]. Add a one-line summary at the top: what changed, what needs attention, and who owns the next step.

For developers and DevOps teams, group findings into the four signals that matter most: reachability, SSL status, response time, and security headers. Where nothing needs action, say the check found no issue in that area rather than implying full coverage.

• [URL]: the exact page or endpoint checked.
• [Check Type]: uptime, SSL, response time, headers, API, CLI, or agent workflow.
• [Status]: pass, review, failed, blocked, or needs human investigation.
• [Issue]: the observable symptom, not an unsupported root-cause claim.
• [Owner]: agency, developer, host, DNS provider, client, or third-party vendor.
• [Next Review Date]: when the team should confirm status again.

The most common mistake is monitoring only the homepage while a checkout, signup, or booking flow silently breaks. Another is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch that before a browser warning does.

For developers and DevOps teams specifically, the recurring miss is treating one clean check as proof the whole site is fine, or fixing an issue without ever writing down what happened — which means the next person repeats the same investigation from zero.

• Tracking too many low-value URLs while missing the ones that matter.
• Skipping notes after an issue is resolved.
• Reporting a status without an owner or next step attached.
• Assuming automation can resolve an incident without human review.
• Treating one clean check as proof that every risk is covered.

Consider a developer confirming production is healthy right after a deployment. A scheduled check flags that the production site is slower than its usual baseline and that a security header is missing. Instead of guessing, the team logs the observation with a timestamp, assigns an owner, and re-checks after the fix ships — turning a vague "something feels off" into a specific, closed-loop task.

MonitorMojo runs website health checks that combine reachability, SSL certificate status, response time, and security header presence in one workspace, so this workflow doesn't require stitching together several separate tools.

The API and CLI make the same checks scriptable for developers and DevOps teams who want them wired into an existing process, while credit-based checks keep it practical to run reviews exactly when they matter — before a client call, after a deploy, or when someone asks whether the production site is healthy. Results still depend on hosting, DNS, and how quickly the responsible team acts on what the check finds.
