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 Meta Box?
Meta Box ships an agent skill so ChatGPT, Claude and Cursor write correct Meta Box code.
Meta Box now offers a free agent skill and a Coding with AI guide so assistants such as ChatGPT, Claude and Cursor produce correct Meta Box code instead of guessing at its API. It follows a week in which customers gained downloads of older and beta builds from their account, and AIO 3.14's view previews, slug-free URLs and login limits.
Rivet vs Meta Box: 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.
Meta Box
5.0DEVOPS
Meta Box ships an agent skill so ChatGPT, Claude and Cursor write correct Meta Box code.
◆ Current state
Meta Box now offers a free agent skill and a Coding with AI guide so assistants such as ChatGPT, Claude and Cursor produce correct Meta Box code instead of guessing at its API. It follows a week in which customers gained downloads of older and beta builds from their account, and AIO 3.14's view previews, slug-free URLs and login limits.
◆ Where it's heading
Meta Box is building two tracks at once: deeper data modeling for WordPress (custom models, relationships, block bindings) and making that model usable by AI tools, starting with July's agent-driven field building and now coding assistants. Release management is also maturing, with rollbacks available to customers.
◆ Prediction
Expect the agent skill to grow to cover custom models and relationships, the areas Meta Box shipped most recently. Whether it ties into the July agent feature is not stated.
