Echo is running two lines in lockstep, and security is what triggers releases
Echo maintains v4 and v5 in parallel and treats security parity as non-negotiable — both of the vulnerabilities in this window were fixed on v5 and backported to v4 within hours. The issues themselves are the same class twice over: values taken from request headers and paths being trusted too readily. Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.

Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.
The pattern that matters is where each vulnerability lived: both sat in code that decides what a request is, before any application logic runs, which is where a web framework's security surface actually is. Feature work is confined to v5 — an optional rate-limiter store context for response headers, core hot-path optimisation — while v4 receives security fixes only, a clean maintenance split with no ambiguity about which line is current.
Expect v5 to keep taking the middleware and performance work while v4 continues receiving same-day security backports, and further hardening around path and header parsing given that two reported issues in a row landed there.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
Rivet is building toward a single answer to a specific question: where does agent-generated, user-facing software actually run? The BYOC move unlocks regulated industries and large enterprises who can't send data to a SaaS control plane. MCP turns Rivet's Actors into something any AI client can discover and call without bespoke integration. Dynamic Apps makes Rivet the runtime, not just the infrastructure, for user-generated software. The through-line is that Rivet wants every AI agent — whether built by a developer or generated at runtime — to run on the Actors primitive with Rivet managing the lifecycle.
BYOC on AWS/GCP is the foundation; Azure support and SOC 2 certification are the logical next steps to close enterprise deals. Expect MCP to expand to more clients (OpenAI Codex, Copilot, Windsurf) as the MCP ecosystem grows, and Dynamic Apps to get versioning and rollback — the missing piece for user-facing production deployments.
