What is Groonga?
Groonga is putting a full-text search engine into WebAssembly and the browser.
Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.
What is Rivet?
Rivet's Rust SDK for Actors is generally available.
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
Groonga vs Rivet: editorial side-by-side
Groonga
5.0DEVOPS
Groonga is putting a full-text search engine into WebAssembly and the browser.
◆ Current state
Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.
◆ Where it's heading
The WebAssembly work is moving piece by piece from the core command to options and plugins, which points toward a usable in-browser search engine. Every WASI item is still marked experimental and not stable.
◆ Prediction
Expect more WASI coverage in the next 16.1.x releases, with the experimental label likely to stay for now.
Rivet
6.3DEVOPS
Rivet's Rust SDK for Actors is generally available.
◆ Current state
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
◆ Where it's heading
Rivet is widening who can build on its actor model while 3.0 matures: a Rust SDK GA lets performance-sensitive teams use it without a TypeScript layer. The platform direction remains S3-only infrastructure for stateful workloads.
◆ Prediction
Expect 3.0 to move toward a stable release and more SDK languages. The entries don't show a 3.0 GA date.
