What is CodeRabbit?
CodeRabbit maps your attack surface — security review moves from PR comments to repository-wide threat modeling.
CodeRabbit is shipping a security product layer alongside its AI code review core. The Attack Surface Map catalogs a repository's entry points, trust boundaries, access controls, and sinks — and marks security coverage stale when PRs touch mapped areas. The AI Deep Scan API and cross-repository guidelines extend the security intelligence further. Alongside these, rate-limit observability, MCP usage APIs for enterprise, and self-hosted updates indicate broad platform maturation.
What is Rivet?
Rivet's Dynamic Apps let you deploy AI-generated apps via V8 isolates — zero-sandbox infrastructure for user-generated code.
Rivet is shipping infrastructure for the agentic application layer: Dynamic Apps (V8 isolates for user-generated apps that scale to zero), Durable Streams for Actors, and an agentOS execution API that runs JavaScript and Python natively rather than through bash. The architecture thesis — V8 isolates instead of container sandboxes — is now production across the Actor, Streams, and Cron layers.

CodeRabbit
6.3DEVOPS
CodeRabbit maps your attack surface — security review moves from PR comments to repository-wide threat modeling.
◆ Current state
CodeRabbit is shipping a security product layer alongside its AI code review core. The Attack Surface Map catalogs a repository's entry points, trust boundaries, access controls, and sinks — and marks security coverage stale when PRs touch mapped areas. The AI Deep Scan API and cross-repository guidelines extend the security intelligence further. Alongside these, rate-limit observability, MCP usage APIs for enterprise, and self-hosted updates indicate broad platform maturation.
◆ Where it's heading
CodeRabbit is moving from 'AI-powered PR review' to 'continuous security intelligence for repositories.' The attack surface map is the most directional signal: it's not a PR-level feature but a repository-level knowledge graph that makes security review systematic rather than ad hoc. The Learnings Write API, cross-repository guidelines, and MCP usage API are all infrastructure for making the system's knowledge accumulate and be programmable.
◆ Prediction
The next move is likely connecting the attack surface map to automated PR blocking rules — flagging PRs that touch high-risk sinks without corresponding verification evidence. The AI Deep Scan API becoming GA is the logical next step after beta.
Rivet
6.3DEVOPS
Rivet's Dynamic Apps let you deploy AI-generated apps via V8 isolates — zero-sandbox infrastructure for user-generated code.
◆ Current state
Rivet is shipping infrastructure for the agentic application layer: Dynamic Apps (V8 isolates for user-generated apps that scale to zero), Durable Streams for Actors, and an agentOS execution API that runs JavaScript and Python natively rather than through bash. The architecture thesis — V8 isolates instead of container sandboxes — is now production across the Actor, Streams, and Cron layers.
◆ Where it's heading
Rivet is building toward a full execution platform for AI-generated code: actors for stateful logic, isolates for sandboxed user code, durable streams for event delivery, and a zero-disk SQLite storage engine for persistence. The Dynamic Apps announcement is the clearest statement of the product's endgame — developers who build products where users generate and deploy their own apps.
◆ Prediction
The next move is pricing and billing for Dynamic Apps runs — the infrastructure is in place, and the V8 isolate model (scale-to-zero, per-request cost) maps naturally to usage-based billing.
