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 Weaviate?
Weaviate patched its whole cloud estate in 17 hours after the eMudhra CA compromise.
Weaviate's October has been security-heavy: v1.39.3 fixed a Google-module credential leak and then a nearObject cross-collection vector disclosure. Now it reports rotating certificates across its customer estate and platform within 17 hours of the eMudhra leak. On the product side, 1.40 brings PathSeer adaptive filtered search, and Engram is now a Claude Code plugin for persistent agent memory.
Rivet vs Weaviate: 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.
Weaviate
5.0DEVOPS
Weaviate patched its whole cloud estate in 17 hours after the eMudhra CA compromise.
◆ Current state
Weaviate's October has been security-heavy: v1.39.3 fixed a Google-module credential leak and then a nearObject cross-collection vector disclosure. Now it reports rotating certificates across its customer estate and platform within 17 hours of the eMudhra leak. On the product side, 1.40 brings PathSeer adaptive filtered search, and Engram is now a Claude Code plugin for persistent agent memory.
◆ Where it's heading
Two threads run in parallel: index and quantization research (HFresh, 4-bit RQ, PathSeer) that lowers memory cost at scale, and an agent-memory layer built on Engram. The security posts suggest Weaviate is preparing to show its operational record to enterprise buyers.
◆ Prediction
Expect 1.40 to reach GA with PathSeer, along with further Engram integrations for other coding agents.
