🛡️ FFS Engine

Powered by Fast Fucking Script. A secure, sandboxed runtime that prevents crashes and malware. Your code runs in the cloud, not on your laptop.

🧠 F3 Skills

Don't write plugins. Equip Skills. Verified, secure capabilities (Stripe, AI, Email) that connect your agent to the internet safely. No npm hell.

⏰ Temporal Core

Built-in Scheduler with WAL Persistence. Schedule tasks dynamically: call.schedule.in("30m", ...). It remembers even if the server restarts.

👻 Hologram

Develop in a Parallel Dimension. F3 creates temporary environments for every edit. Test your code live without ever breaking production.

🔑 Zero-Pass Auth

Forget passwords. F3 generates Ed25519 Asymmetric Keys linked to your DNS. Deployment and Login are cryptographic proofs of ownership.

💾 Data Mesh

Connect to SQLite, Postgres, or Excel Files instantly. Name a folder [schema.table.id] and F3 auto-loads the data.
