2026 OpenClaw Pre-Deploy Inspection in Practice:
Lighthouse, Dead-Link Detection & Baseline Accessibility on Remote Mac
Release windows compress performance, broken links, and accessibility into the same hour. This HowTo shows how to reproduce a single OpenClaw-driven pipeline on a remote Mac: OpenClaw orchestrates Lighthouse, dead-link detection, and baseline accessibility checks so your remote Mac CI node enforces one quality gate before merge or deploy. Below: scope, task graph, example thresholds, artifact layout, retries, and FAQ—with a no-login purchase path at the end.
01 ① Define the inspection scope
Freeze the pre-deploy baseline: canonical hosts, staging vs production URLs, and a route seed list (home, auth, checkout, settings, flagged routes). Feed sitemap or a route manifest into the crawler, with capped depth and concurrency for your CI budget.
Document auth (cookies, read-only test users) and which paths need login. Third-party analytics or widgets are usually observe-only unless first-party. Split block-the-merge vs warn-only rules and commit them beside the OpenClaw workflow.
- Base URL, environment label, and build ID / Git SHA injected into every report filename.
- Robots.txt and “do not crawl” path prefixes shared with the link checker.
- Max depth, max URLs, and per-host concurrency aligned with Mac CPU and egress.
- Block vs warn lists versioned with the pipeline YAML or OpenClaw task bundle.
02 ② OpenClaw task orchestration
OpenClaw is the scheduler and glue between CLIs. Use a serial graph: (1) health check; (2) Lighthouse on seeds (mobile or desktop), JSON/HTML to a fixed dir; (3) dead-link detection with status, final URL, referrer; (4) accessibility via axe-core, Pa11y, or Lighthouse a11y—pick one primary signal.
Each stage emits JSON and non-zero exit on breach; OpenClaw aggregates logs and can signal upstream CI via SSH or callback. Pin Node and Chromium (.nvmrc, CHROME_PATH). See Lighthouse alerts and pre-deploy smoke tests.
03 ③ Thresholds and quality gates
Thresholds are policy—version the table below for your product. Use median of three Lighthouse Performance runs; keep LCP/CLS comparable run to run. Different error types get different severity: internal 404 = hard fail; whitelisted third-party timeout = warn.
| Check | Example threshold | On failure |
|---|---|---|
| Lighthouse Performance (mobile) | Score ≥ 80 (median of 3) | Block merge or require two-owner waiver |
| Lighthouse Accessibility category | Score ≥ 90 | Warn if only contrast noise; block on missing names/roles |
| LCP (lab, same throttling) | ≤ 2.5 s | Downgrade to warn if a single marketing LP spikes |
| CLS (lab) | ≤ 0.1 | Block on layout shift in checkout |
| Internal dead links | 0 × 404 / 410 / timeout / TLS failure / DNS failure | Fix or remove href; no silent ignore |
| Mixed content (active) | 0 | Force HTTPS or fix CDN rules |
| Axe severity (or equivalent) | Serious = 0; Moderate ≤ 3 | Moderate overflow needs ticket + deadline |
Dead-link error types: 404/410 → content/routing; 5xx → upstream/rollback; ETIMEDOUT/ECONNRESET → retry then infra; ERR_CERT_* → TLS/clock; ENOTFOUND → DNS/typo. Always store the referrer URL.
04 ④ Report archiving and retries
Store under artifacts/YYYY-MM-DD/<short-sha>/ with lighthouse/, links/, a11y/; upload as CI artifacts. Put run ID, Node/Chromium versions, and throttling in root manifest.json.
Retry only transients: e.g. three backoff steps (5s / 15s / 45s) per URL. Same internal URL failing all retries = stable defect. For Lighthouse variance, compare to the last good median on the same Mac image.
- Keep allowlists for external domains next to the gate table in Git.
- Dead-link reports must include status code, final URL, and referrer.
- Performance: log throttling, emulation, and Chromium build string per run.
05 ⑤ FAQ
Staging scores differ wildly from production. Align CDN, compression, cache headers, and geographic egress; run both from the same remote Mac region where possible and document deltas in the report footer.
External partners time out often. Downgrade to warning or add a hostname allowlist; keep internal links on the hard gate.
Design conflicts with strict a11y rules. Serious violations must never be waived silently; use a ticketed exception with owner and expiry. Moderate issues can ship with a dated backlog if policy allows.
Why remote Mac? Predictable Chromium timing and the same box for Safari/WebKit checks when you widen gates beyond Chrome-only signals.
OpenClaw on a remote Mac lets web ops and frontend release owners chain Lighthouse, dead-link detection, and accessibility rules into one reproducible remote Mac CI gate: define scope, run a clear task order, enforce a versioned threshold table, archive JSON/HTML proof, and retry only transient errors. When you need a dedicated node for long audits and artifact retention, use our no-login checkout and docs below.
