A typesafe TypeScript and Next.js codebase with server-side rendering, clean components, Postgres tables on Supabase and row-level security already configured.
Chat, text generation, image generation, speech-to-text and text-to-speech modules with support for major model providers, so you can pick and swap LLM or media APIs.
Supabase authentication with Google sign-in and magic links, Stripe and Lemon Squeezy checkout, plus Loops or Resend transactional email integrations.
Pre-built marketing pages, waitlist templates, SEO metadata, automated sitemaps and an admin dashboard for managing users, usage and plans.

Ship your AI SaaS in days, not months
Authentication, rate limits, API usage monitoring, an admin dashboard and transactional email are pre-built so you can focus on your product rather than plumbing.
A pre-configured Pinecone setup lets users upload PDFs, docx, xls and other text files as embeddings for retrieval-augmented chat and analysis.
Out-of-the-box REST routes work with OpenAI, Anthropic, Groq or self-hosted Llama, with advanced retries and fallbacks to keep requests succeeding.
Stripe and Lemon Squeezy integrations handle charging, webhooks, subscription updates and product provisioning from day one.
