Bucardo review
A focused, self-hosted choice for selective PostgreSQL table replication.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bucardo is an open-source, Perl-based database replication system for two or more databases. It is designed for teams that need asynchronous, table-based replication in a self-hosted environment, especially PostgreSQL deployments. It supports one-way, multi-source, multi-target, and multi-way configurations, with replication focused on selected tables or sequences rather than an entire database by default. Bucardo runs on Unix-like systems such as Linux and macOS.
Its strongest capability is configuration depth for selective replication. Database triggers track changed rows, while full-copy, pushdelta, and swap sync types support different replication approaches. Conflict handling can use standard or custom handlers, and monitoring covers replication status and row transfers. This makes Bucardo a fit for controlled PostgreSQL replication topologies where object selection and conflict behavior matter. The listed database ecosystem includes PostgreSQL, Drizzle, MongoDB, MySQL, MariaDB, Oracle, Redis, and SQLite, although PostgreSQL remains the primary platform described for the system.
Bucardo's self-hosted design suits organizations comfortable managing Unix-like infrastructure, database triggers, daemons, and replication configuration. The website lists Bucardo 5.6.0, while its documentation pages are dated 2020, so teams should evaluate documentation currency during adoption. Choose Bucardo when free, open-source replication and fine-grained table selection are priorities. Choose an alternative when you need a managed service, a broader integration ecosystem, or a replication workflow that does not depend on trigger-based change tracking.
Bucardo pros and cons
