Trellara
Every transaction. Every database. Provably accounted for.
Logical replication in PostgreSQL is easy to start and hard to trust. One stalled consumer holds WAL and puts the source under pressure. A destination drifts, and nothing tells you. Proving a replica actually matches usually means writing your own reconciliation and hoping it is right.
That gets worse with every database you add — and fleets add databases quickly.
Trellara is an open-source verification and operations layer for PostgreSQL logical replication. It sits between source databases and their destinations, and installs nothing inside the database itself.
What it does
- Protects source databases from the pressure caused by stalled consumers.
- Moves committed transactions with their boundaries intact.
- Provides verifiable proof that every destination has converged with the source.
Built for fleets
- Vertical SaaS and ISVs running a database per customer.
- Retail and logistics operations whose databases are frequently offline.
- AI platforms with thousands of tenant databases.
- Data teams that need one verified stream feeding several consumers.

Apache-2.0 licensed. Begin with a small diagnostic against a database you already run — no broker to stand up first, and nothing to install server-side.
