What is Builder.io?
Builder.io is rebuilding around the agent: MCP, design-system indexing, and credits to match.
Builder.io has spent 2026 converting a visual editor into an agent workspace. The design system is indexed once and shared across the agent, design mode, and the insert menu; Figma frames import in bulk; a Builder MCP server puts prototypes into the repo and pushes branches back. Recent releases are less about new canvas features than about what the agent knows and what it costs to run.
What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

Builder.io
5.0DEVOPS
Builder.io is rebuilding around the agent: MCP, design-system indexing, and credits to match.
◆ Current state
Builder.io has spent 2026 converting a visual editor into an agent workspace. The design system is indexed once and shared across the agent, design mode, and the insert menu; Figma frames import in bulk; a Builder MCP server puts prototypes into the repo and pushes branches back. Recent releases are less about new canvas features than about what the agent knows and what it costs to run.
◆ Where it's heading
Two lines run in parallel. One is reach: MCP, the Claude design handoff, and multi-frame Figma imports all widen what can flow into Builder from outside. The other is commercial: Agent Credits are now a unit customers top up independently of their plan, which is what a company does when agent consumption rather than seats is becoming the thing being sold. Collaboration features - element-level comments, Peer Review - are being fitted around that agent loop rather than competing with it.
◆ Prediction
Expect the credit meter to become more prominent as usage-based agent pricing, and inbound integrations to keep arriving faster than editor features.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
