What is Rivet?

Rivet pivots from actor backend to a coding-agent OS, and is building the ecosystem to match.

Rivet began as an actor and serverless backend platform — RivetKit, Rivet Actors, Rivet Compute — and has spent the last month reorienting around agentOS, a WebAssembly-based Linux environment for running coding agents without a heavy sandbox. The June and July releases show both threads running in parallel: native language SDKs (Rust, Effect) for Actors, and a fast-maturing agentOS that now has its own package registry.

What is Tigris?

Tigris is positioning object storage as the substrate for AI agents

Tigris is building S3-compatible object storage with a distinct thesis: buckets as forkable, snapshot-able substrate for AI agents. Concrete releases in this window are solid storage primitives — soft delete with 90-day recovery, a streaming tar bundle API to pull thousands of objects in one request, prefix-filtered lifecycle rules, and a CLI migrate command. But much of the feed is engineering-blog material (agent sandboxes, forking LangGraph state, a git server stored in a bucket) that argues the thesis rather than shipping a feature.

Rivet pivots from actor backend to a coding-agent OS, and is building the ecosystem to match.

◆ Current state

Rivet began as an actor and serverless backend platform — RivetKit, Rivet Actors, Rivet Compute — and has spent the last month reorienting around agentOS, a WebAssembly-based Linux environment for running coding agents without a heavy sandbox. The June and July releases show both threads running in parallel: native language SDKs (Rust, Effect) for Actors, and a fast-maturing agentOS that now has its own package registry.

◆ Where it's heading

The center of gravity is shifting from hosting stateful actors to being the runtime coding agents execute inside. agentOS went from a v0.2 sandbox alternative to shipping a package registry and a sub-millisecond package manager in under two weeks, a sign Rivet wants to own the developer surface around agent execution, not just the compute underneath it.

◆ Prediction

Expect agentOS to keep accreting ecosystem pieces — more registry content and tighter orchestration — while the Actors SDKs settle toward maintenance. A likely next move is deeper coupling between agentOS and Rivet Compute so agents run on Rivet's own cloud.

Tigris is positioning object storage as the substrate for AI agents

◆ Current state

Tigris is building S3-compatible object storage with a distinct thesis: buckets as forkable, snapshot-able substrate for AI agents. Concrete releases in this window are solid storage primitives — soft delete with 90-day recovery, a streaming tar bundle API to pull thousands of objects in one request, prefix-filtered lifecycle rules, and a CLI migrate command. But much of the feed is engineering-blog material (agent sandboxes, forking LangGraph state, a git server stored in a bucket) that argues the thesis rather than shipping a feature.

◆ Where it's heading

The direction is clear and consistent: make storage the durable home for agents that otherwise live in disposable sandboxes — copy-on-write bucket forks, agent shells, provider-agnostic SDKs with snapshots and forks built in. The product releases keep S3 parity table-stakes (soft delete, lifecycle, migration) while the narrative work stakes out the agent-substrate position. Worth noting that the changelog leans heavily on blog posts, so raw entry cadence overstates shipping velocity.

◆ Prediction

Expect more agent-oriented primitives around forking and snapshotting to graduate from blog demos into shipped API surface; the entries point that way but don't pin a specific next release.
