The codebase is structured the way a senior engineer would build it. Not a tutorial project — a production scaffold you fork and ship.
Vector embedding pipeline built on AI SDK 6 with pgvector in Supabase. Chunk → embed → store → retrieve. Fully typed. Drop in your documents and the agent has long-term memory from day one. Streaming retrieval, no boilerplate.
Auth, multi-tenancy, agent orchestration, vector memory, credit guards, billing — integrated and tested, not bolted together the night before launch.
Auth.js v5 with full organisation-level isolation. Every user, every agent run, every data row scoped to a tenant from day one. RLS everywhere.
ReAct loop with streaming tool calls. Configurable per-agent: model, tools, system prompt, knowledge base. Visible reasoning chain in the UI.
PDF and TXT ingestion, automatic chunking, pgvector embeddings, semantic retrieval. Agents read your documents before every run without extra config.
Pre-run balance checks, per-run deduction, usage logging per agent. Runs block automatically at zero in a single atomic transaction. No race conditions.
Lemon Squeezy handles billing as Merchant of Record — VAT compliance across 50+ countries handled for you. Credit top-ups, payment history, invoice download, webhook handling, all wired.
End-to-end TypeScript. Zod validation on all agent I/O. Database schemas fully typed via Supabase codegen. Refactor with confidence from day one.
No VC round. No team. One developer, shipping until it's production-ready. Every line written between shifts.
