Agent Vault is an open-source credential broker from Infisical that solves one of the nastiest unsolved problems in AI agent security: AI agents are non-deterministic and vulnerable to prompt injection attacks that could trick them into leaking secrets. The solution is elegant — Agent Vault never gives credentials to the agent at all. Instead, it acts as an HTTPS proxy, intercepting the agent's outbound API calls and injecting credentials at the network layer. The flow is simple: give the agent a scoped session token and set HTTPS_PROXY to Agent Vault's local server. The agent calls APIs normally; Agent Vault transparently swaps in the real credentials before the request leaves the machine. The agent literally cannot leak what it never had. AES-256-GCM encryption with optional Argon2id password wrapping protects the vault, and all proxied requests are logged (method, host, latency) without recording sensitive bodies. Works out of the box with Claude Code, Cursor, Codex, custom Python/TypeScript agents, and any HTTP-speaking process. Infisical is a credible backer — they already run one of the most popular open-source secrets managers. This is MIT-licensed with enterprise features planned. For teams deploying agents in sandboxed environments, this is the missing security primitive.

Open Agents (Vercel Labs)
Vercel's open blueprint for durable cloud coding agents with git & sandboxing

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.
Reviewer scorecard
“The network-layer injection approach is architecturally correct and I'm annoyed I didn't think of it first. This should be standard infrastructure for any team giving agents real API access. The fact that Infisical is behind it gives me confidence it won't be abandoned after a week.”
“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 proxy-based approach introduces a local MITM that itself becomes a high-value attack target. If Agent Vault is compromised, every credential it holds is exposed simultaneously. The API is explicitly unstable ('subject to change') — wait for a stable release before baking this into CI/CD pipelines.”
“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.'”
“Prompt injection is going to be the SQL injection of the agent era. Tooling that bakes in zero-knowledge credential handling at the infrastructure level — rather than bolting it on in prompts — is exactly the architecture shift the industry needs. Expect this pattern to become a compliance requirement.”
“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.”
“For creators running agents that touch their Shopify store, social APIs, or payment processors, this is genuinely peace of mind. I don't want to think about whether my coding agent just got manipulated into printing my Stripe key. Agent Vault makes that a non-problem.”
“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.”
