-- **Discord**: https://discord.gg/uCqHvxjU83 -- **Email**: mike@cortexlinux.com +
+Is it free? -## Why This Matters +Yes! Community edition is free and open source (Apache 2.0). Enterprise subscriptions will be available for advanced features. +
-**Market Opportunity**: $50B+ (10x Cursor's $9B valuation) +
+Is it secure? -- Cursor wraps VS Code β†’ $9B valuation -- Cortex wraps entire OS β†’ 10x larger market -- Every data scientist, ML engineer, DevOps team needs this +Yes. All commands are validated and executed in a Firejail sandbox with AppArmor policies. AI-generated commands are checked against a security allowlist. +
-**Business Model**: Open source community edition + Enterprise subscriptions +
+Can I use my own LLM? -## Founding Team +Currently supports Claude (Anthropic) and OpenAI. Local LLM support is planned for future releases. +
+ +
+What if something goes wrong? + +Every installation is tracked and can be rolled back with `cortex rollback `. +
