About StackFirefly
From the official readme · v0.24.10Description
Find WordPress problems that uptime monitoring misses.
StackFirefly provides error tracking and site monitoring for WordPress and WooCommerce. Firefly Agent connects your website to a dashboard for investigating PHP errors, browser JavaScript errors, missed scheduled tasks and email delivery problems—even when your homepage is still online.
Built for site owners, developers and agencies, it brings monitoring evidence and recent changes together so you can understand what happened, investigate the cause and verify recovery.
A StackFirefly account and connection to the external service are required. Service availability and allowances depend on your account plan. Review current plans at https://stackfirefly.com/pricing before connecting. This plugin is the local connector; monitoring history, incident correlation and AI-assisted diagnosis run in the hosted service.
What you can monitor
- PHP error tracking and JavaScript errors: review grouped issues with sanitized messages, file and line details, affected page paths and stack traces where available.
- WP-Cron and scheduled tasks: check cron execution, WooCommerce Action Scheduler failures and overdue background jobs.
- REST API and AJAX connectivity: investigate failed background requests and origin connectivity problems that a homepage uptime check can miss.
- Email delivery monitoring: run user-requested or configured email tests to check whether a test message reaches the monitoring receiver.
- Security monitoring: review known plugin/theme vulnerabilities, security headers, bounded core/uploads file scans and privacy-minimized configuration changes.
- Lighthouse performance monitoring: follow PageSpeed test results, LCP, FCP and other available metrics over time through the hosted service.
AI-assisted suggestions use collected evidence; they are not proof of a cause or recovery. This plugin does not automatically repair your site, edit configuration files or update other plugins. Available evidence varies by error, connection and site configuration.
WordPress Multisite is supported through network activation. Pair the main website, then choose which subsites to monitor in StackFirefly. Initial discovery supports up to 100 websites. Selected websites use individual site allowances; shared core/configuration findings appear on the main website.
From an error to a next step
Repeated reports are grouped into issues so you can review available evidence, follow recent changes, and record your investigation. Acknowledgements, reported fixes and verified recovery stay distinct. Deterministic checks establish recovery; an AI suggestion does not mark a problem as fixed.
Connect your AI assistant with MCP
Connect StackFirefly to ChatGPT, Claude, Codex or another compatible remote MCP client. Your assistant can review selected sites’ issues, available evidence, recent changes and Lighthouse results without copying reports between tools.
Choose the workspace, sites and permissions. Connections are read-only by default. Optional permissions allow issue acknowledgements, reported-fix notes and verification requests, not changes to WordPress. Revoke access in StackFirefly at any time; newly added sites are not shared automatically.
This optional hosted-service feature requires manual setup and an AI account that supports remote MCP connections. It is separate from StackFirefly’s built-in AI diagnosis. Setup guide: https://stackfirefly.com/docs#ai-connections
External services and data
StackFirefly — https://stackfirefly.com
Pairing explicitly connects the site to StackFirefly over HTTPS. Before pairing, the plugin does not upload monitoring telemetry. Clicking the account/setup link passes the site’s home URL, WordPress installation URL and display name to StackFirefly to prefill setup. Paired sites send authenticated heartbeats (normally every five minutes) and bounded batches of observations; inventory is sent periodically or when changes are detected. Retries are bounded. Reliable scheduled delivery requires working WordPress cron or a host-managed cron runner.
Data may include site URLs and name, Agent/platform versions, PHP and web-server information, installed component names/slugs/versions and update state, status codes and timings, scheduler counts/ages, sanitized error messages, relative file/asset paths and line numbers, bounded stack frames, safe public page paths, third-party resource hostnames, file fingerprints and recognized configuration-setting change categories. Browser collection is served locally, is rate-limited and does not create visitor tracking identifiers. Requested PHP traces are bounded and omit function arguments.
Passwords, API secrets, cookies, authorization headers, form contents, order/customer records, raw request bodies and complete response bodies are not intentionally collected. File contents and private configuration values stay on the site. Diagnostic sanitization limits the detail available; not every error includes a trace or page location.
StackFirefly uses this data for monitoring, issue history, notifications and requested diagnosis. Its external probes request configured public pages. Performance tests, when requested or scheduled in the service, submit the public test URL to Google PageSpeed Insights. The plugin itself does not call Google PageSpeed Insights. AI-provider processing is described in the service privacy notice. If you authorize an external AI client through MCP, the selected monitoring context is shared with that client under your chosen permissions and the AI provider’s own terms and privacy settings. MCP tools do not return Agent credentials or pairing keys; the plugin does not connect to those AI clients directly.

WordPress.org checksum service — https://api.wordpress.org/core/checksums/1.0/
After pairing, WordPress’s checksum API may be used during scheduled core integrity checks. WordPress version and locale are sent to retrieve reference checksums. WordPress.org receives the requesting server’s connection metadata. No local file contents are sent to that service.

Updates
The WordPress.org package uses native WordPress plugin updates. Earlier direct-download packages use StackFirefly’s signed release channel. Both use the same plugin folder and saved connection settings. Do not delete/uninstall the old plugin to migrate; use WordPress’s upload-and-replace flow using the directory package. See the FAQ.
Installation
- Install and activate Firefly Agent. For Multisite, network-activate it.
- Open Settings → StackFirefly (Network Admin → Settings for Multisite).
- Click “Connect to StackFirefly” and keep the WordPress tab open.
- Sign in or create an account, verify your email, and approve the displayed website. Choose a workspace if prompted.
- Return to the WordPress tab. It connects automatically and shows an Open dashboard link.
If you start in StackFirefly, save your website first, then follow the installation steps above. Your existing unpaired site is reused. Older installations can use “Connect another way (pairing key)”. Connection requests expire after 30 minutes; start again if needed.
Frequently asked questions
Does this work without a StackFirefly account?
No. Firefly Agent is a connector for the hosted monitoring service. Account plans and current allowances are listed at https://stackfirefly.com/pricing.
Can this help investigate PHP or JavaScript errors?
Yes. StackFirefly groups repeated errors into issues and shows the diagnostic context available for each report. Depending on the error, this can include the affected page, script or PHP file, line number and a sanitized trace. Some browser errors expose only limited information. Monitoring helps you investigate; it does not automatically fix plugin or theme code.
Can I check why WP-Cron or WooCommerce scheduled actions are failing?
The Agent reports cron and Action Scheduler observations, including failed jobs and overdue work where supported. StackFirefly presents the evidence and verification guidance. Direct cron checks may be inconclusive when a host or firewall blocks verification; missing data is not proof that cron has failed.
Does this fix WordPress emails not sending?
It helps test and investigate email delivery. It does not replace an SMTP plugin or configure your mail provider. A monitoring test checks delivery of that test message, not every message sent by your website.
Does performance monitoring make my website faster?
StackFirefly shows Lighthouse/PageSpeed results, performance history and available improvement details. You or your developer make the recommended changes. It does not add caching, compress images or optimize code automatically.
Is WooCommerce required?
No. General WordPress checks work without WooCommerce. WooCommerce-specific observations require supported WooCommerce APIs.
Does activation alone send site data?
No monitoring telemetry is uploaded until pairing. Opening the account/setup link shares the website details shown in the plugin to prefill registration. Review them before continuing.
Can I move from the direct-download plugin without reconnecting?
The directory package keeps stackfirefly/stackfirefly.php and the existing settings, credentials and local queue. Upload the WordPress.org ZIP and choose to replace the installed version. Do not delete the plugin first: uninstall removes local connection data. Native WordPress updates apply after replacement. App-triggered updates from the private release channel are not available in the directory package.
What happens if I deactivate or uninstall?
Deactivation stops the plugin’s monitoring hooks and scheduled cycle while retaining local connection data for reactivation. Uninstall removes the local Agent connection and queue; it does not delete your StackFirefly account or hosted history. Manage or remove the site in StackFirefly separately.
Where do I get help?
Visit https://stackfirefly.com/docs for setup guidance or https://stackfirefly.com/contact for support. Do not post pairing tokens, credentials or unsanitized logs in public support threads.
