What is CodeRabbit?

CodeRabbit now reads Claude Code's .claude/rules, so one rule file guides agent and reviewer.

CodeRabbit now reads Claude Code rules from .claude/rules, applying a rule only to the files in its paths frontmatter or to an inferred scope when none is given. It follows the rename of Autopilot to Autofix and of the old comment fixer to Fix comments. Underneath, the product has moved past comment-only review, with a CLI that launches cloud Coding Agent tasks, Deep Scan across linked repositories, and a Security check that admins can require to block merges.

What is Rivet?

Rivet adds Hosted VMs, so agentOS sandboxes are addressable by ID over plain HTTP.

Rivet ships a named launch roughly weekly around its Actors runtime. October brought Pi 1.0 hosting at 0.82 MB of RAM per session, Rivet 3.0 with S3 as its only dependency, and Pi Durable checkpointing every model call to SQLite. On October 12 agentOS 0.4 added durable Hosted VMs created by ID and controllable from RivetKit or plain HTTP, with scoped JWTs for direct client access.

CodeRabbit vs Rivet: editorial side-by-side

C7.5

CodeRabbit now reads Claude Code's .claude/rules, so one rule file guides agent and reviewer.

◆ Current state

CodeRabbit now reads Claude Code rules from .claude/rules, applying a rule only to the files in its paths frontmatter or to an inferred scope when none is given. It follows the rename of Autopilot to Autofix and of the old comment fixer to Fix comments. Underneath, the product has moved past comment-only review, with a CLI that launches cloud Coding Agent tasks, Deep Scan across linked repositories, and a Security check that admins can require to block merges.

◆ Where it's heading

CodeRabbit is repositioning from reviewer to agent that finishes the work, and it is lining up with the coding agents that write the code it reviews. Reading .claude/rules extends guideline support from its own config to the files teams already keep for Claude Code. Security review is turning into an enforcement layer wired into branch protection, and GitLab parity follows each new capability.

◆ Prediction

Expect support for other agents' rule files to follow the Claude Code addition, and merge blocking to extend from GitHub to GitLab. The entries don't say which agent formats come next.

7.5

Rivet adds Hosted VMs, so agentOS sandboxes are addressable by ID over plain HTTP.

◆ Current state

Rivet ships a named launch roughly weekly around its Actors runtime. October brought Pi 1.0 hosting at 0.82 MB of RAM per session, Rivet 3.0 with S3 as its only dependency, and Pi Durable checkpointing every model call to SQLite. On October 12 agentOS 0.4 added durable Hosted VMs created by ID and controllable from RivetKit or plain HTTP, with scoped JWTs for direct client access.

◆ Where it's heading

The releases converge on one position: Rivet as the durable home for agent harnesses in your own backend, with tools isolated in a sandbox. Hosted VMs give that sandbox side a managed, addressable form, reusing the scoped-JWT model from September; BYOC, auth and tracing are the enterprise prerequisites around it.

◆ Prediction

Expect more agentOS releases that tie Hosted VMs to the Pi harness and Actors, plus 3.0 self-hosting guides; at the current cadence another launch within two weeks is likely.
