WAL-native capture
Stream logical replication events from PostgreSQL into a searchable change history without adding triggers, middleware hooks, or schema changes to the application database.
AuditOwl
AuditOwl is a managed PostgreSQL audit logging service that captures changes from the write-ahead log and makes them searchable. It helps teams review database history without triggers or application code changes.
Database change logs captured from the WAL
AuditOwl is a managed service for PostgreSQL that records database changes from the write-ahead log and turns them into a searchable change history. It is positioned for teams that need to review who changed what, when, and how without adding triggers or touching production writes.
The product captures inserts, updates, and deletes from the WAL, enriches them with metadata, and exposes the resulting history through a console and API. The site also emphasizes side-by-side diffs, transaction grouping, and export options for investigations, debugging, audits, and compliance work.
Why AuditOwl
Search and query
Filter change history by schema, table, operation, time range, or transaction, and ask audit questions against the captured data.
Fully managed service
AuditOwl handles ingestion, storage, retention, and scaling so users can connect a database, choose what to capture, and start querying.
Before and after values
For updates and deletes, the product shows old and new row state so teams can reconstruct what changed and when.
Low overhead capture
Logical decoding reads the WAL asynchronously, which the site says keeps the OLTP workload fast while changes flow in near real time.
Compliance-oriented history
The product stores immutable, append-only change logs with retention policies for audit trails, compliance work, and investigations.
Common use cases
Investigate what changed
Review database history during an incident or customer support case by filtering changes to the relevant table, time range, and transaction.
Rebuild row history
Compare old and new row values for updates and deletes when reconstructing how a record reached its current state.
Support audits and retention workflows
Use immutable change logs and retention policies to support audit trails and compliance requests such as data access reviews.
Capture operational changes
Track direct SQL, migrations, and admin scripts that application-level logging can miss, since WAL capture sees committed changes at the database layer.
Pros and Cons
Pros
- Captures committed database changes from the WAL rather than relying on application-level logging.
- Avoids triggers, middleware hooks, and application code changes in the described setup.
- Provides filtering, diffs, transaction grouping, and export tools for reviewing history.
- Managed ingestion, storage, retention, and scaling reduce operational work for the team.
- Near real-time asynchronous capture is designed to keep production workloads fast.
Cons
- The source material is specific to PostgreSQL, so support for other databases is not shown.
- The product is presented as early access, and the pricing page does not list published plans or prices.
FAQ
What does AuditOwl connect to?
AuditOwl is a managed service that records PostgreSQL database changes from the write-ahead log. The source material does not describe self-hosting or on-premises deployment options.
How does setup work?
The setup flow shown on the site is: connect a PostgreSQL database, let AuditOwl capture changes from a logical replication slot, and then query the resulting history in the console or API.
How do teams review changes?
The site says AuditOwl can be used through a console or API, and its UI is designed to filter changes by schema, table, operation, time, and transaction.
Is pricing available?
The pricing page available in the source does not show plan names, tiers, or prices. It only indicates the product is in early access and invites users to request access.
