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 Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

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.
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
