SaaSpark Anthropic
MCPSkillsClaude models — large language models built for safety and reliability.
- Category: ai-model-apis
Why this tool
Claude is currently strongest for long-context reasoning and agentic workflows.
OpenAI
Frontier LLMs (GPT family) via a unified inference API.
- Category: ai-model-apis
Why this tool
Multi-provider routing protects against rate limits and provider outages.
Vercel AI SDK
TypeScript toolkit for building AI-powered apps with streaming.
- Category: ai-agents-mcp
Why this tool
Streaming, structured outputs, and provider abstraction in TypeScript.
Pinecone
Managed vector database for production-grade RAG.
- Category: vector-db-rag
Why this tool
Managed, low-latency vector search — essential when RAG enters the product.
Clerk
Drop-in authentication and user management for modern apps.
- Category: auth-identity
Why this tool
Authentication is not where you should be inventing.
Supabase
MCPOpen-source Firebase alternative with Postgres, auth, storage.
- Category: database-baas
Why this tool
Postgres + auth + storage; the cheapest BaaS to grow from MVP to seed.
Vercel
Frontend hosting and serverless platform built for Next.js.
- Category: hosting-deployment
Why this tool
Edge functions + streaming responses for token-by-token UX.
Stripe
Payments infrastructure for the internet.
- Category: payments-billing
Why this tool
Metered usage billing is a Stripe sweet spot.
PostHog
Open-source product analytics, session replay, feature flags.
- Category: product-analytics
Why this tool
Track prompt completions, retention, and conversion in one place.
Sentry
Application monitoring and error tracking for every layer.
- Category: error-monitoring
Why this tool
AI features fail in subtle ways — Sentry catches what users won't tell you.
Why this stack
You're building on top of LLMs. Provider-route from day one (Claude + OpenAI), abstract via the Vercel AI SDK, and stream tokens to keep perceived latency low. Costs should track usage — Stripe metered billing handles that natively.
