Open Agents is Vercel Labs' open-source reference implementation for building persistent cloud coding agents. It demonstrates a three-tier architecture: a chat UI layer, a durable workflow layer using the new Vercel Workflow SDK, and isolated sandbox VMs with snapshot/resume. The result is an agent that doesn't lose its state when your laptop closes — it keeps working in the cloud and you can pick up the conversation when you're back. The reference implementation includes git operations (clone, branch, commit, PR creation), voice input via ElevenLabs integration, session sharing via a shareable URL, and a real-time log stream so you can watch what the agent is doing. It's designed to be forked and adapted rather than used as-is — think of it as Vercel's opinionated answer to "how should a cloud coding agent be architected?" What makes this notable isn't the feature list — it's the source. Vercel is the dominant deployment platform for web developers, and when Vercel shows you how to build something, thousands of developers follow the pattern. Open Agents is likely to become the de facto reference architecture for the next generation of coding agent products built on Vercel infrastructure.

AI agent that remembers every run — built for long-running research and optimization loops

Remoroo is an AI agent purpose-built for long-running autoresearch and optimization workflows. The core loop is simple: give it a codebase and a measurable target, and it iterates autonomously — patch → run → eval → repeat — while maintaining a persistent memory of every attempt. It directly attacks the most frustrating failure mode in agentic coding: the agent that forgets what it already tried and circles back to dead ends hours into a job. The memory architecture stores code style preferences, project context, experimental hypotheses, and outcome measurements across sessions. When an agent run is interrupted or the job takes multiple days, Remoroo picks up with full context rather than starting from scratch. This is particularly valuable for ML training optimization, benchmark improvement tasks, and code performance tuning where individual runs take hours and the value is in the accumulated learning across dozens of attempts. Remoroo surfaced on Hacker News and the Hugging Face forums with strong interest from ML researchers and engineers who've been struggling with the same problem in their own workflows. It's early-stage, but it addresses a gap that every team running long-horizon AI agents has hit.
Reviewer scorecard
“The snapshot/resume sandbox is the piece everyone keeps reinventing badly. Having a reference implementation from Vercel that shows the right way to do durable agent state is genuinely useful — I'll fork this as a starting point for my next agent project.”
“The patch-run-eval-repeat loop with persistent memory is exactly what's missing from existing coding agents. I've wasted days watching agents revisit approaches they already tried because they lost context. Remoroo's memory-as-infrastructure approach is the right abstraction. Would ship for any multi-day optimization task today.”
“This is a Vercel marketing vehicle dressed as open source. The reference architecture conveniently requires Vercel Workflow SDK, Vercel AI SDK, and Vercel deployments at every layer. 'Open source' here means 'open to study, closed to portability.'”
“Very early — the website is sparse and there's no published information about the memory architecture, storage backend, or how context degradation is handled over hundreds of runs. The HN discussion is promising but the product itself is pre-documentation. Check back in three months.”
“Platform wars in the agentic era will be won by whoever makes agent deployment easiest. Vercel publishing this pattern is them planting a flag: 'cloud coding agents live here.' The developer gravity they already have makes this a self-fulfilling prophecy if they execute.”
“Persistent, searchable agent memory across sessions is one of the fundamental missing pieces for agents that operate at human research timescales. Remoroo's focus on measurable targets and outcome-based memory makes it more rigorous than naive conversation logging. This points toward agents that genuinely compound knowledge over weeks and months.”
“Session sharing via URL is the killer feature for collaborative creative work. Being able to send someone a link to watch your agent in action — or hand off a session to a collaborator — unlocks a whole category of async creative workflows.”
“Interesting for technical research workflows but the use case is narrow — it's optimizing code and ML runs, not creative or design work. The tool needs to demonstrate how it generalizes beyond quantitative optimization before it's compelling for broader creative applications.”
