For AI-built apps · Supabase first · Private pilot

Nocturne watches your AI-built app while you sleep.

The autonomous operations and scaling layer for AI-built software. Lovable, Bolt or Claude Code built it. Nocturne keeps it safe, healthy and ready for growth, and always asks before it acts.

Build fast. Sleep better.

The Night Report

Wake up to this, not to a fire.

Every morning, a calm plain-English briefing: what stayed healthy, what needs attention, where growth is heading, and the one fix worth approving. Not another dashboard. A daily ritual.

And when traffic takes off, Nocturne has already seen it coming: capacity forecast, optimisation proposed, one tap to approve.

The problem

Build is automated. Operate is not.

AI solved software creation. It did not solve production operations. Apps ship in an afternoon with unsafe databases, missing row-level security, slow queries nobody notices, no backup discipline, and no idea what happens when traffic multiplies.

CVE-2025-48757

303 endpoints across 170 Lovable projects exposed user data through missing row-level security: names, phone numbers, API keys and payment details.

Replit · Jul 2025

An AI coding agent deleted a live production database during a code freeze. The rollback worked. The trust did not.

Every one of these apps has an owner who found out too late, or has not found out yet.
What Nocturne does

Guard. Operate. Scale.

01 · Guard
Stay safe

Security, permissions, RLS coverage, backups and risky agent behaviour. Dangerous changes are caught before they land.

02 · Operate
Stay healthy

Slow queries, errors, connection issues, unhealthy services and drift: the day-to-day maintenance nobody was hired to do.

03 · Scale
Absorb growth

Rising load detected, bottlenecks forecast; indexes, pool sizes and compute recommended before demand becomes an outage. Spend-capped, always.

How · deterministic checks all night › AI wakes on anomaly › plain-English fix › approval, then earned autonomy › full audit log
How it works

Approval first. Autonomy earned.

01
Connect

One click, via Supabase's official OAuth. Scoped access to platform metrics and logs. Never your database credentials.

02
Watch

Deterministic checks run all night against the platform APIs. Boring, cheap and relentless. AI wakes only when something drifts.

03
Report

A plain-English Night Report every morning, and real-time alerts when it cannot wait. No jargon, no dashboards to learn.

04
Approve

Every fix starts approval-only. Each action type earns autonomy through repeated clean approvals, with spend caps and a full audit log.

Pricing

Reassurance, priced like a coffee habit.

Questions

The trust bit, in plain English.

What access does Nocturne need?
Nocturne connects through Supabase's official Management API with scoped OAuth. It reads platform metrics, advisories and logs. It never holds your database credentials, and it is read-only until the moment you approve a specific fix.
Will it change things without asking?
No. Every action type starts approval-only. If you approve the same class of fix repeatedly, you can let Nocturne handle that class automatically; every action is spend-capped and written to an audit log you can read. Autonomy is earned, never assumed.
Which platforms does it support?
Supabase first, because that is where most AI-built apps live. Neon, Convex and Firebase are next on the roadmap, with any Postgres to follow.
What is in the free Health Check?
A plain-English score across security, RLS coverage, slow queries, scaling risk, backups and usage anomalies, ending with an honest "would I launch this?" verdict and the shortlist of fixes that matter.
When does the pilot start?
Now. We are recruiting 10 AI-built apps and 3 agencies for the private pilot. Join the waitlist below and say a little about what you are running; pilot places are confirmed by email.
