immudb vs Manticore Search: at a glance
What is immudb?
immudb 1.11.0 added PostgreSQL compatibility — tamper-evident storage now accessible to ORM-based stacks.
immudb is in a 1.11.x maintenance cycle after the substantial 1.11.0 release, which added PostgreSQL ORM compatibility (pg_catalog, information_schema), structured audit logging with tamper-proof JSON events, and a new --audit-verif flag. The 1.11.2 maintenance release fixes a transaction survival issue when a statement fails before execution — a correctness fix for edge cases in transaction handling. The v2.0.0-RC1 from early 2025 introduced a different architecture (new indexing layer, simplified API), but 1.11.x appears to be the active production track.
What is Manticore Search?
Manticore 29.9.0 adds chunked multi-vector embeddings and mmap columnar defaults
Manticore Search is in active pre-release hardening after the feature-dense 29.9.0 drop, which added chunked and multi-vector auto-embeddings, float_vector_array support, and mmap columnar defaults. Weekly patch releases (29.9.3–29.9.6) are stabilizing concurrency, memory, and dependency surface. The ES-compatible ingestion path has also received correctness fixes for hybrid search filters and bulk error handling.

immudb
2.5DEVOPS
immudb 1.11.0 added PostgreSQL compatibility — tamper-evident storage now accessible to ORM-based stacks.
◆ Current state
immudb is in a 1.11.x maintenance cycle after the substantial 1.11.0 release, which added PostgreSQL ORM compatibility (pg_catalog, information_schema), structured audit logging with tamper-proof JSON events, and a new --audit-verif flag. The 1.11.2 maintenance release fixes a transaction survival issue when a statement fails before execution — a correctness fix for edge cases in transaction handling. The v2.0.0-RC1 from early 2025 introduced a different architecture (new indexing layer, simplified API), but 1.11.x appears to be the active production track.
◆ Where it's heading
The PostgreSQL compatibility push is the clearest directional signal: immudb is trying to become accessible to developers using standard ORMs without learning immudb's native API. Combined with the structured audit logging, the pitch is a tamper-evident backend that behaves like PostgreSQL for existing toolchains. The v2.0.0 architecture rework remains an open question — whether it reaches GA or gets merged back into the 1.x line is unclear from the releases shown.
◆ Prediction
A stable v2.0.0 release or clear abandonment of the v2 branch in favor of continued 1.x enhancements is the next decision point. The PostgreSQL compatibility work will likely expand to cover more pg_catalog views needed by common ORMs.

Manticore 29.9.0 adds chunked multi-vector embeddings and mmap columnar defaults
◆ Current state
Manticore Search is in active pre-release hardening after the feature-dense 29.9.0 drop, which added chunked and multi-vector auto-embeddings, float_vector_array support, and mmap columnar defaults. Weekly patch releases (29.9.3–29.9.6) are stabilizing concurrency, memory, and dependency surface. The ES-compatible ingestion path has also received correctness fixes for hybrid search filters and bulk error handling.
◆ Where it's heading
Manticore is building toward a self-hosted AI search infrastructure layer — not just a search engine with vector capability bolted on. Chunked embeddings with configurable tokenization limits, multi-vector per document, and cloud-credential-aware S3 backups signal a deliberate push into production RAG deployments. The mmap columnar default change follows this direction: fewer manual knobs, better out-of-the-box throughput.
◆ Prediction
The next likely moves are further hardening of the ES-compatible /_bulk path now that the Fluent Bit and duplicate-create edge cases are patched, and a production deployment guide targeting RAG use cases. A named stable release of the 29.9.x series is plausible within weeks.
