A look at popular open-source AI agents, with what to know before you try one. Just for fun. As of Nov 7, 2026.
GitHub description “Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace.”
Our read it holds many tenants’ chats and files in one place, so an isolation bug matters more here than in a single-user tool.
If you use it Run 1.15.0 or newer if you self-host. Change the default secret key and database credentials, and keep the console off the open internet.
GitHub description “Open-source Python library for AI browser agents, plus Browser Use Cloud.”
Our read an agent that drives a logged-in browser can do whatever you can do there. That is the appeal and the risk.
If you use it Don’t point it at logged-in accounts or internal sites. Use allowed_domains, a throwaway browser profile and a sandbox, on 0.1.45 or newer.
GitHub description “No fortress, purely open ground. OpenManus is Coming.”
Our read an agent that can run commands on your machine should live somewhere you can throw away.
If you use it Run it in a disposable VM or container with its Docker sandbox on. Keep API keys out of its workspace and don’t aim it at untrusted web pages.
GitHub description “Automate browser based workflows with AI”
Our read a tool that runs generated code needs a strong sandbox, so it is worth knowing its record before you expose a server.
If you use it Check the project’s security advisories before you run it. Keep any server behind a firewall, and add a human-approval step before anything gets submitted or paid.
Our read it asks to be connected to your messages and accounts all day, and a skill marketplace adds a second place for trouble to come from.
If you use it Don’t connect real email, chats or credentials until you understand the setup. Never expose its gateway to the internet, and read a skill before installing it.
Our read n8n usually holds logins for Drive, Slack, GitHub and more, so whatever gets in can reach all of them.
If you use it Keep self-hosted instances off the open internet, stay patched, and give each connection only the permissions it needs.
GitHub description “Your AI second brain. Self-hostable.”
Our read a “second brain” stores your notes and documents, which is exactly what you would not want exposed.
If you use it If you self-host, read the project’s security advisories for your version, don’t expose its port to the internet, and turn on API keys.
GitHub description “Assemble, configure, and deploy autonomous AI Agents in your browser.”
Our read an archived project is fine to look at, less fine to host for other people.
If you use it Don’t host it for others or pay for it. If you try a demo, use a throwaway key with a low spending limit.
Our read the original “let the loop run” idea. It is here for its place in history, not for a security record.
If you use it Treat it as a historical demo. Don’t run it on a machine with real API keys, files or network access.
GitHub description “SuperAGI - A dev-first open source autonomous AI agent framework.”
Our read with no recent release, treat it as a demo, not something to run with real data.
If you use it Keep it off the internet and don’t share one install between several people.
