You don't need a warehouse to build business apps on PostgreSQL.
PostgreSQL already runs your product and your operations, so why copy it into another system just to build an app on it?
Connect Astrato and you've got live business apps – for your team or embedded in your product – that write straight back: approve a record, change a status, kick off a workflow, and the database updates on the spot.
What teams build on Astrato + Postgres
Data Apps & Workflows
Write back to PostgreSQL from any app and chain no-code actions into guided workflows – approvals, forecasts, scenario plans. Act on the numbers without leaving the app.
Customer-Facing Apps
Embed pixel-perfect, white-labelled apps in your product in days – multi-tenant by design, isolated at PostgreSQL's own row level.
Guided Self-Service
Business users explore live PostgreSQL data through no-code apps on a governed semantic layer – self-service that never breaks the numbers.
Your product & operations run on Postgres. Why not your business apps, too?
Astrato brings the action – live business apps with writeback, straight on Postgres.
Read live and write back to the same PostgreSQL.
This is where a dashboard stops being a report and becomes a tool. Instead of exporting to a spreadsheet to change anything, your team approves a request, updates a status or kicks off a workflow right where they see the data – written to Postgres as a governed action: inside the permissions you already enforce, validated on entry and fully audited. The change is live the moment it's made, ready for whatever reads it next.
Describe the app. Nash builds it on PostgreSQL.
Nash builds a governed semantic layer first – the metrics and definitions you own – then builds the app from a plain-English prompt, live on Postgres. You choose the LLM and limit what it can see, so every number traces back to a definition you trust. Prefer Claude, ChatGPT, Codex or Cortex Code? Connect them through MCP and they work from the same governed definitions.
Build data apps, not just dashboards.
Seeing the spike on real-time data isn't enough – you need to act on it. Astrato turns dashboards into operational data apps: write back to Postgres, chain no-code actions into guided workflows, and fire alerts, exports or triggers the moment the numbers move. Insight and action in the same place, no engineering required.

Astrato inherits your PostgreSQL security.
The roles, grants and row-level security you've already set in Postgres decide what Astrato can see and do – there's no second permission system to maintain. Writeback runs as governed, audited SQL, and Astrato stores none of your data: it stays in Postgres, reached over SSL with IP allow-listing.

Frequently asked questions
Do we need a data warehouse to build apps on PostgreSQL?
No. Astrato queries your PostgreSQL database live – no warehouse to stand up, no ETL, no second store to keep in sync. Apps run on the database that already powers your product, on the current data, so there's nothing between the question and the answer.
Won't running Astrato on our production PostgreSQL slow the app down?
You stay in control of that. Astrato queries PostgreSQL and renders the result – it doesn't extract or duplicate your data – so you manage analytics load the way you already manage everything else: point Astrato at a read replica, or at a least-privilege role, if you want reporting traffic kept clear of production. Either way it's querying live.
Can writeback overwrite our production data?
Only where you allow it. A writeback executes as governed SQL against the tables you designate, inside the roles and grants PostgreSQL already enforces – point Astrato at a least-privilege role and it physically can't touch anything else. Inputs are validated before they land, unauthorised users never see the control, every change is logged with user, timestamp and payload, and you can require an approval before a write commits. It's a controlled action, not an open door.
Does it work with our cloud PostgreSQL?
Yes. Astrato speaks standard PostgreSQL, so the same connection works on any PostgreSQL-compatible database – cloud or on-prem, managed or self-hosted. Point it at your tables and you're live.
How do security and governance work?
Astrato works inside the roles, grants and row-level security you've already set in PostgreSQL – there's no second permission system to maintain. Your data stays in PostgreSQL (Astrato stores none of it), connections use SSL and IP allow-listing, and writeback runs as governed, audited SQL. On the Astrato side: ISO 27001, SOC 2, HIPAA and GDPR, with SSO.
Can we embed apps in our own product?
Yes. Pixel-perfect, white-labelled apps embed in your product, multi-tenant by design and live on PostgreSQL. Your customers get apps that look like your product, with the same governed writeback and access controls behind them.
