Developer Sentinel
Bring your own AI key · pick any model · human-approved fixes

Fire the 2 a.m. firefight. Hire an AI engineer for every WordPress site you own.

Developer Sentinel watches your client sites, reproduces the bug, finds root cause, and proposes a fix — that you approve before it touches production. Average incident: 7 minutes, not 3 hours.

No card required. No autonomous fixes — every change is reviewed and reversible.

From first ticket to monthly retainer — covered.

Catch it first

Find the incident before your client emails you.

Scheduled health sweeps surface SSL expiry, malware signatures, PageSpeed regressions, and fatal errors — and open the incident automatically. You hear about problems from Sentinel, not from an angry Slack DM.

Resolve it cleanly

Diagnose, propose, approve — in one thread.

Sentinel pulls real evidence (debug.log, HTTP probes, plugin/theme state), reasons to root cause, and proposes a labelled fix. You approve. Staging first when possible. Every action snapshotted and reversible.

Prove the value

Send the client-ready report on the 1st of the month.

White-label PDF with every incident, what changed, time-to-fix, and uptime delta. Turn a $40/mo care plan into something clients can actually see — so they renew instead of asking what they're paying for.

The Problem

Clients churn at month 6. Because care plans look like an invoice with nothing behind it.

They aren't leaving because the site broke. They're leaving because every month they get a bill — and no proof that anyone was actually watching. By the time the real incident hits, trust is already gone.

01 / 04 · Invisible work

Clients can't see what you do for $40/mo.

WordPress admin shows no history. Updates run silently. When the client asks 'what did you actually do last month?' you scramble through Slack and memory. Invoices without proof feel like overhead.

$4,800
ARR lost when a single $400/mo retainer cancels.
02 / 04 · Reactive firefighting

Every incident starts at 2 a.m.

Site goes down. Client calls. You SSH in, tail logs, deactivate plugins one by one. Three hours later it works again — and there's no record of what changed, why, or how to prevent it next time.

3 hrs
Average WordPress incident burned at $95/hr senior dev rate.
03 / 04 · Flying blind

25 sites, no single pane of glass.

Each site has its own WP admin, its own debug.log, its own plugin list. Checking the portfolio means 25 logins. You find out about the broken site, the expired SSL, the active CVE — when the client tells you.

10 hrs
Ops drag every month at ~25 min per manual site check × 25 sites.
04 / 04 · Silent CVEs

The vulnerability is already public.

Wordfence published the CVE on Tuesday. By Friday it's being exploited at scale. Your client's outdated Elementor / WooCommerce / contact-form plugin is sitting unpatched — and the breach response will cost more than the entire year of retainer.

  • • 6 incidents × ~3 hrs investigation
  • • $95/hr senior WP dev rate
  • • Slack threads, no audit trail
  • • Reactive only — fires already burning
With Developer Sentinel
$99/mo
  • 7-min average resolution
  • Proactive health sweeps catch issues first
  • Every fix logged & reversible
  • White-label PDF reports for clients
Net savings
$29,592/yr
  • • ~$1,184/site/year recovered
  • • ~210 dev hours back per year
  • • Resell as a $20/site/mo care plan → +$6k/mo revenue
What the agent actually does

A senior WordPress engineer, on call for every site you run.

Not a chatbot wrapper. The agent reads real evidence from your sites, reasons to root cause, and proposes a labelled fix you approve before anything runs.

Diagnose any incident

Reads debug.log, WP Site Health, .htaccess, plugin/theme state, HTTP headers, and recent changes. Binary-searches plugin conflicts. Root-causes WSOD, 500s, nonce/REST failures, login loops, stuck “maintenance” pages.

Fix safely, with approval

Toggle plugins, edit content & SEO meta, clear stale .maintenance, propose .htaccess patches. Every action labelled Safe / Needs-approval / Risky — snapshotted and reversible in one click.

WooCommerce operations

Checkout & Action Scheduler health, product edits (price, stock, SKU, sale dates), variations, featured images, and SEO meta across Yoast, RankMath, SEOPress, AIOSEO.

Content & page edits

Update titles, excerpts, and bodies on posts, pages, and products. Create new pages with builder-aware multi-section HTML — no copy-paste from ChatGPT into wp-admin.

Proactive watch

Scheduled sweeps for SSL expiry, malware signatures, PageSpeed regressions, and CVE matches against your installed plugin versions. You hear about issues from Sentinel — not from the client.

Performance triage

Autoload bloat detection, cron analysis (stuck vs missing handlers), and on-demand HTTP request logging so you can reproduce the slow page and see exactly where the time went.

Built for

The people actually keeping WordPress sites alive.

If you make money keeping other people's WordPress sites running, this was built for you.

Primary fit

Solo WP freelancers & care-plan operators

5–30 sites

You're the whole ops team. Sentinel kills the 2 a.m. firefight and turns your $40/mo care plan into something the client can actually see — a white-label monthly report with every incident, fix, and minute saved.

Strong fit

Small WordPress agencies

1–10 devs, 25–150 sites

One pane of glass across the portfolio. Junior devs handle L1 incidents because the agent gathers the evidence and proposes the labelled fix — senior just approves. Audit log on every action.

Great fit

WooCommerce store owners

1–3 stores

Product, inventory, and SEO edits without hiring a dev for every small change. Checkout health checks catch Action Scheduler backlogs before customers do. Safe by default — nothing runs without your approval.

Not the right fit: enterprise multi-region ops, fully autonomous self-healing, or anyone who wants AI pushing to prod unattended. Every Sentinel action requires a human approval \u2014 by design.

Real evidence, not guesses

The agent pulls WP Site Health, debug.log tails, HTTP probes, plugin/theme state, and WAF headers — then reasons to a root cause.

Approval-gated remediation

Every action is labelled Safe, Needs-approval, or Risky. Nothing runs on production without an explicit human approval recorded in the audit log.

One-click rollback

Each action snapshots prior state. Reverse a plugin toggle, .htaccess edit, or theme switch with one click — staging-first whenever possible.

Bring your own key

Your AI key. Your model. Your bill — at cost.

Sentinel doesn't resell tokens or mark up inference. Plug in your own OpenAI, Anthropic, or Google Gemini key once and the agent uses it for every diagnosis — so you keep full control of spend, data routing, and rate limits.

Your keys, your account

Paste OpenAI, Anthropic, or Google API keys in workspace settings. Inference is billed directly by the provider — no token markup, no surprise bills from us.

Any frontier model, per incident

Default to fast + cheap (Gemini Flash, GPT-5 mini) for triage. Switch a single incident to GPT-5, Claude Sonnet, or Gemini Pro when the bug is gnarly — without changing your workspace default.

Data stays on your terms

Evidence (debug.log, plugin state, probes) is sent only to the provider you chose, under your account's data-handling agreement. Swap providers per incident, per workspace, or per client.

Anthropic · Claude Sonnet, Haiku
Google · Gemini 2.5 Pro, Flash

How BYOK works

Three steps from pasting a key to revoking it. No middlemen, no token reselling.

  1. 01

    Paste your key

    Go to Workspace Settings → AI Providers and paste an OpenAI, Anthropic, or Google Gemini API key. Keys are encrypted at rest and scoped to that single workspace.

  2. 02

    Sentinel calls the provider directly

    When you run a diagnosis, the agent sends the prompt + evidence straight to the provider you chose using your key. We don't proxy through a shared pool, log raw prompts, or train on your data.

  3. 03

    Revoke any time

    Clear the key from Workspace Settings to immediately stop all inference, or revoke it in your OpenAI / Anthropic / Google console. Existing incidents keep their audit log; no future calls succeed.

BYOK, answered

How keys are stored, what data leaves your workspace, and who can see what.

Where are my API keys stored?

Encrypted at rest in our backend database, scoped to a single workspace. Keys are never written to logs, never returned to the browser after save (we show a masked preview only), and never shared across workspaces — even within the same account.

Who can see or use my key?

Only workspace owners and admins can paste, rotate, or clear keys. The decrypted key is loaded into memory only for the duration of a single AI call, then discarded. Other team members can use the AI without ever seeing the key value.

What data gets sent to the AI provider?

Only the evidence the agent needs for the current incident: your prompt, relevant debug.log tails, plugin/theme state, HTTP probe results, and Site Health output. We don't send database contents, customer PII from your WP install, or unrelated incidents.

Does Sentinel use my prompts or keys for anything else?

No. We don't train models on your prompts, don't read them for analytics, and don't share keys with any third party. Inference goes directly from our backend to the provider you chose, billed to your provider account.

Do OpenAI / Anthropic / Google train on my data?

By default, API calls from paid OpenAI, Anthropic, and Google AI Studio / Vertex keys are not used to train their models. You're bound by the provider's data-processing agreement on your own account — not ours. Check each provider's API data-usage policy for the definitive terms.

What happens when I revoke a key?

Clearing the key in Workspace Settings stops all future AI calls within seconds. Revoking it in the provider console is even stronger — the next call returns a 401 from the provider itself. Past incidents and their audit logs are preserved; nothing is retroactively deleted.

Built for the tickets that ruin your week.

Six classes of WordPress emergencies that Developer Sentinel resolves end-to-end.

Security

Outdated plugin with active CVE

Sentinel flags the vulnerable plugin, proposes the update, takes a snapshot, and verifies the site still renders post-update.

Outage

White screen of death after deploy

Tails fatal.log, identifies the offending plugin/theme, and offers a one-click safe-mode rollback while you notify the client.

Email

"WooCommerce emails not sending"

Inspects SMTP config, sends a probe, reads bounce headers, and proposes the exact mailer + DNS change to fix delivery.

Performance

Site is suddenly slow

Runs TTFB probes, finds the slow query or external API call, and recommends caching or plugin replacements — with measured deltas.

Maintenance

Bulk plugin updates across 25 sites

Queues updates per site, runs them with approval, and posts a single client-ready report with what changed and what passed health checks.

Monitoring

Proactive 24/7 health sweeps

Scheduled scans open incidents before your client emails you. PageSpeed regressions, SSL expiry, malware signatures — all surfaced.

From "white screen" to fixed, in one conversation.

    01

    Connect

    Install the companion plugin, paste the pairing token. Onboarding warns you if Cloudflare AI bot rules or a WAF will block the round-trip.

    02

    Report

    Describe the issue in plain English — or let scheduled health sweeps surface it for you.

    03

    Diagnose

    The agent runs read-only diagnostics, reproduces the failure, and explains the root cause in plain language.

    04

    Approve & verify

    Approve the proposed fix. We apply on staging first when available, then production, then re-run the failing check.

Real reactions from the first wave of studios running Developer Sentinel across their portfolio.

"Our on-call dev used to lose a full Saturday a month to plugin conflicts. Sentinel resolved the last seven incidents before he even opened Slack. He literally asked if his job was safe."
