What is immudb?
immudb made itself speak Postgres — while its announced v2 rearchitecture sits unfinished.
immudb is a tamper-evident database that recently taught itself the PostgreSQL wire protocol in earnest: pg_catalog and information_schema resolvers, PostgreSQL compatibility functions, SHOW emulation, and subquery support, enough for Django, SQLAlchemy, GORM, and ActiveRecord to introspect it. Its own verification primitives — state, row and transaction proofs, history — are now callable as SQL functions over that same wire. The follow-on 1.11.1 release adds opt-in value-level audit verification and index-only COUNT(*).
What is Tigris?
Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.
This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.

immudb made itself speak Postgres — while its announced v2 rearchitecture sits unfinished.
◆ Current state
immudb is a tamper-evident database that recently taught itself the PostgreSQL wire protocol in earnest: pg_catalog and information_schema resolvers, PostgreSQL compatibility functions, SHOW emulation, and subquery support, enough for Django, SQLAlchemy, GORM, and ActiveRecord to introspect it. Its own verification primitives — state, row and transaction proofs, history — are now callable as SQL functions over that same wire. The follow-on 1.11.1 release adds opt-in value-level audit verification and index-only COUNT(*).
◆ Where it's heading
The direction is unmistakable: stop asking developers to adopt a bespoke API and instead present as Postgres with integrity guarantees attached. Every recent addition either removes an adoption barrier (ORM introspection, compatibility functions) or makes the integrity story operationally usable (structured audit logging, SHA-256 value re-verification during audit cycles). Sitting against that is a v2.0.0 release candidate announcing a page-based indexing redesign and multi-ledger storage that has not reached GA while the 1.11 line kept shipping — the rearchitecture is announced, not delivered.
◆ Prediction
Expect continued PostgreSQL surface-filling on the 1.11 line, since each compatibility gap is the concrete thing blocking an ORM. What the entries do not support is a confident call on v2: the RC has been outpaced by 1.11 releases, and nothing in the changelogs indicates whether it is being finished or quietly shelved.
Tigris
5.0DEVOPS
Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.
◆ Current state
This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.
◆ Where it's heading
The writing is doing product work. Each protocol post establishes a problem — SigV4's canonicalization and clock skew, presigned URLs as deliberate replay attacks, S3 egress pricing on ClickHouse restores — and positions Tigris behavior as the answer, which makes the blog a migration funnel rather than a changelog. The architecture post is a different move: publishing the FoundationDB composition is a credibility play aimed at buyers who need to believe a newer object store can hold multi-region data.
◆ Prediction
Expect the protocol-critique-then-Tigris-answer format to continue, with the egress-cost framing recurring as the clearest paid migration path. Feature announcements will likely stay embedded in essays rather than appearing as release notes.
