What is Phaser?
Phaser 4 landed a ground-up WebGL rewrite and is now filling in the renderer it built
Phaser shipped version 4 in April 2026 after a long release-candidate run, replacing the v3 pipeline system with a node-based renderer, unifying FX and masks into one filter system, and adding SpriteGPULayer for very large sprite counts. The releases since have been additive work inside that new architecture: CustomContext for reaching into DrawingContext at render time, Mesh2D for batched textured triangles, stencil and alpha-strategy game config, and a patch cleaning up stencil defaults and ESM build breakage.
What is Rivet?
agentOS is becoming infrastructure other agent platforms build on, not a Rivet feature
Rivet has consolidated around agentOS, a virtual operating system that gives agents a terminal, filesystem and networking on WebAssembly and V8 isolates inside a backend you already run, instead of a container or VM per agent session. The surrounding pieces are now in place: a package registry, an install path measured in microseconds, durable timezone-aware cron for actors, and an execution API that runs JavaScript and Python directly rather than shelling out to bash. Underneath it, the team is building its own storage layer — a zero-disk SQLite engine that keeps writes local-fast while cold pages tier out to object storage.

Phaser 4 landed a ground-up WebGL rewrite and is now filling in the renderer it built
◆ Current state
Phaser shipped version 4 in April 2026 after a long release-candidate run, replacing the v3 pipeline system with a node-based renderer, unifying FX and masks into one filter system, and adding SpriteGPULayer for very large sprite counts. The releases since have been additive work inside that new architecture: CustomContext for reaching into DrawingContext at render time, Mesh2D for batched textured triangles, stencil and alpha-strategy game config, and a patch cleaning up stencil defaults and ESM build breakage.
◆ Where it's heading
The v4 rewrite is holding, and the follow-up releases are exposing renderer internals as supported API rather than hiding them — CustomContext, stencil configuration and alpha strategies all hand advanced users direct control over GL state that v3 kept private. The bug pattern in 4.2.1, where stencil options silently did nothing and namespace access broke the ESM build, is the expected cost of a young renderer meeting real games.
◆ Prediction
Expect continued additive 4.x releases exposing more render-node and filter surface, with patches trailing each one to fix defaults and ESM packaging as the new paths get exercised.

agentOS is becoming infrastructure other agent platforms build on, not a Rivet feature
◆ Current state
Rivet has consolidated around agentOS, a virtual operating system that gives agents a terminal, filesystem and networking on WebAssembly and V8 isolates inside a backend you already run, instead of a container or VM per agent session. The surrounding pieces are now in place: a package registry, an install path measured in microseconds, durable timezone-aware cron for actors, and an execution API that runs JavaScript and Python directly rather than shelling out to bash. Underneath it, the team is building its own storage layer — a zero-disk SQLite engine that keeps writes local-fast while cold pages tier out to object storage.
◆ Where it's heading
The argument Rivet keeps making is an economic one: a sandbox holds a whole container open while the agent sits idle waiting on inference, which is the cost structure isolates already solved. That case is no longer only Rivet's to make — Vercel's Eve and Flue both shipped agentOS support within two days of each other, which moves agentOS from a product surface toward a layer other vendors depend on. The recent work has shifted accordingly, from proving the runtime to filling in what a runtime needs to be depended on: execution APIs, scheduling, and now durable storage.
◆ Prediction
With the execution API and storage engine landing back to back, the next gap in the stack is state and data access for agents built on agentOS — expect the SQLite tiering work to surface as a product surface actors can call, not just an engineering post. A third platform adoption announcement in the same changelog format is the other pattern the entries support.
