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.

What is Manticore Search?

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

Rivet vs Manticore Search: editorial side-by-side

R

DEVOPS
7.5

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.

M5.0

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

◆ Current state

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

◆ Where it's heading

The 31.x line is in steady correctness work, with several tags a week and each fixing one edge case in real-time tables, backups or query paths. No feature work has shown up in the feed since 31.0 began.

◆ Prediction

Expect more single-fix 31.0.x tags; the entries give no sign of when the next feature release lands.
