Autonomous database diagnostics
Database issues, diagnosed.
Resolution on a silver platter.
dbexpertAI runs expert-curated detection paths every 90 seconds across five SQL database systems and delivers root cause, evidence, and resolution steps — no human in the loop.
First database free, for life. $50/month each after that, self-serve.
No credit card, no sales call. Windows, macOS or Ubuntu — the agent runs inside your network and pairs itself back.
read-only agent · on-prem · deterministic · 90-second detection cadence
// symptom detected
Checkout API p99 latency 8.4s (baseline 240ms)
// root cause
Autovacuum overdue on public.orders — dead/live tuple ratio 0.34 → stale statistics and heap bloat flipped the planner off the index
// diagnostic evidence
- ├ n_dead_tup / n_live_tup = 0.34 on public.orders (pg_stat_user_tables)
- ├ last_autovacuum 26h ago, against sustained write churn
- └ plan flip confirmed: idx_orders_created no longer chosen
// resolution steps
- 1. VACUUM (ANALYZE) public.orders now
- 2. Raise autovacuum_vacuum_cost_limit for this table
- 3. Set table-level autovacuum_vacuum_scale_factor = 0.02
Watch it work
Connect a database. Wait 90 seconds. Read the diagnosis.
The monitoring gap
Monitoring tells you what is happening. Diagnosis tells you why.
Dashboards show symptoms
CPU is up, latency is up, connections are climbing. Monitoring tools render the symptoms beautifully — and leave the 2–4 hour investigation to you.
Alerts fire without causes
A page at 3am tells you a threshold was crossed. It does not tell you that autovacuum starved, a plan flipped, or replication silently fell behind.
dbexpertAI delivers the why
Root cause, diagnostic evidence, and resolution steps — delivered autonomously in 90 seconds, across all five SQL systems we cover.
How it works
Connect. Wait 90 seconds. Read the diagnosis.
01
Connect a read-only agent
A read-only, on-prem agent connects to your database. Your data never leaves your network, and nothing can write to production.
02
Detection paths run every 90 seconds
Expert-curated diagnostic logic — the same investigation paths a senior DBA walks, encoded deterministically — runs continuously against your live system.
03
Root cause lands on your desk
When something is wrong you get the root cause, the diagnostic evidence behind it, and concrete resolution steps. Not an alert. Not a dashboard. A diagnosis.
Deterministic, not probabilistic
Expert-curated detection paths.
Not an ML black box.
Every diagnosis follows a detection path — the same investigation a senior DBA runs, encoded so it executes in seconds. Written with AI assistance, tested on real production servers by real DBAs, and signed before release. Same input, same output, every time. You can read the evidence and check the reasoning. Here's exactly how one gets made.
The alternative — training ML models on metrics and hoping the correlations hold — has been tried. OtterTune, the best-funded attempt, shut down in 2024. We wrote up the lessons.
// what deterministic buys you
- reproducible — same symptoms, same diagnosis, every run
- explainable — every conclusion ships with its evidence
- auditable — detection paths are written down, not weights
- no model at runtime — AI helps write them; nothing guesses when they run
- safe — read-only checks; nothing guesses on production
Decision-ready, not just diagnosed
Every fix arrives with the risk of applying it.
Knowing the root cause is half a decision. The other half is: what happens if I ignore this, and what happens if I don't? Every dbexpertAI finding carries a severity — so you know what's actually hurting you and in what order. Every resolution path carries a risk level, whether each step is reversible, its rollback, and how long it takes.
Which is what you actually need to decide whether this is a junior's ticket for Tuesday or a senior with a staging pass and a change window. Nothing runs against production on its own: paths are supervised or manual, and your team applies them.
- low risk
1. VACUUM (ANALYZE) public.orders
reversible · no rollback needed · ~4 min
- medium risk
2. Raise autovacuum_vacuum_cost_limit
reversible · rollback: restore prior value · ~1 min
- high risk
3. Set table-level autovacuum_vacuum_scale_factor
requires confirmation · test on staging first
Reporting
And a history you can put in front of your own management.
Scheduled PDF and spreadsheet reports — daily, weekly or monthly, delivered to your inbox: what was found, what was fixed, what's still open. The evidence that things are getting better, in a form you can forward to someone who is never going to read an execution plan.
See what you getCoverage
Five SQL databases. One diagnostic engine.
The SQL systems that run production — same 90-second cadence, same root-cause-first reporting across your whole estate. More engines are on the roadmap; tell us which one you need.
Security posture
Read-only. On-prem. Your data never leaves your network.
The agent runs inside your infrastructure with read-only credentials. It cannot write to your databases, and your data is not shipped to us — diagnoses are computed where the data lives. Zero risk to production is the design constraint everything else obeys.
Pricing
$50 per database, per month.
Self-serve, flat, and honest: your first database is free — not a trial, for life — and every one after that is $50/month. Running a serious fleet, or want setup and hands-on help? That's the enterprise conversation.
// back of the envelope
| first database | $0 — free for life |
| 5 databases | $200 / mo |
| junior DBA (fully loaded) | $15,000–25,000 / mo |
| coverage | 24/7, every 90 seconds |
