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 Sonic?
Sonic yanks two releases in a day, then ships faster ingest and new count commands.
Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.
Rivet vs Sonic: editorial side-by-side
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.
Sonic
2.5DEVOPS
Sonic yanks two releases in a day, then ships faster ingest and new count commands.
◆ Current state
Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.
◆ Where it's heading
The 1.x line is moving fast on ingest performance and correctness for high-scale and non-English users, at the cost of some unstable releases. Experimental APIs are being tested in production before they reach official builds.
◆ Prediction
Expect the experimental high-scale PUSH features to graduate out of the feature flag in a later 1.x; when is unclear.
