AI agents are increasingly capable of working independently, but they struggle to securely communicate and collaborate with agents owned by other people or organizations. Existing agent frameworks lack a common way for agents to establish trusted connections, coordinate tasks, and safely exchange information across organizational boundaries. This creates significant challenges around interoperability, trust, prompt injection, governance, and controlling what an external agent is allowed to do.

Premortem stress-tests a startup idea before you build it. Paste the idea and six AI agents attack it at once, covering the market, technology, competition, unit economics and more, then a seventh writes a memo with the findings. It takes under 90 seconds on average, so you can change direction while it is still cheap.

OpenAPPA is an open-source information-flow policy engine for AI agents. It enforces deterministic rules about where data may go, designed to stop data exfiltration caused by prompt injection or model hallucination without breaking the agent's normal work. It works with coding agents such as Claude Code and with agent platforms, has a playground, ready-made policy batteries, observability and benchmarks.

Recurse makes it easy to build an agent app with Python tools, deploy it, and publish it as an MCP server you can use from Claude, Codex or any MCP client. They handle the hosting. You can start from your coding agent with a single prompt, or install the SDK and deploy from the command line. Examples include a text-to-podcast agent, an invoice generator and an email validator.

Vestra is an office of AI agents that learn about you, grow with you and are accessible from anywhere. You hand over tasks, routines and whole responsibilities, and come back to finished work. Agents cover founders' inbox and calendar, sales follow-ups, marketing campaigns, content, customer support, finance and invoicing, engineering triage, recruiting, operations and research.

Incredible is a desktop AI for macOS and Windows that does tasks on your computer the way you would: it clicks and types in your browser, files and apps, so the busywork gets done while you do something else. You hold a key and say what you need, and Incredible works directly inside your apps to complete it. There is a free plan to try it, with paid plans for heavier use.

Captain Code is a local orchestration layer that lets developers manage multiple AI coding agents and models from a single terminal interface. Instead of manually switching between Claude, Codex, Cursor, Grok, and other models, Captain classifies each task and routes it to the appropriate agent or team. It can optimize model selection based on task difficulty, cost, quality, and availability, while preserving context when work is handed from one agent to another. It also supports parallel tasks, repeated workflows, multi-agent reviews, model-specific commands, and automatic recovery when an agent hits usage limits. Captain Code runs locally and is open source, with support for existing subscriptions, API models, and open-source models.
