LM Studio
A desktop app for discovering, downloading, and running open-weight LLMs locally with a GUI and a local OpenAI-compatible server.
Lovable
An AI app builder that turns natural-language prompts into shippable full-stack web apps.
Milvus
An open-source vector database built for billion-scale similarity search, with a distributed architecture and a wide menu of index types.
Modal
Serverless AI infrastructure in pure Python — GPU functions with sub-second cold starts, secure sandboxes for agent code, batch jobs, and per-second billing.
N8n
Fair-code workflow automation with native AI — a visual canvas plus code, 400+ integrations, and LangChain-based agent nodes; self-host free or cloud per-execution.
OpenRouter
A hosted unified API to hundreds of models from many providers, with one key, one bill, and automatic fallbacks.
Pinecone
A fully managed, serverless vector database for similarity search and RAG — no nodes to run, indexes to tune, or infrastructure to operate.
Portkey
An AI gateway and LLMOps platform: route to many LLMs through one API with caching, retries, fallbacks, load balancing, guardrails, and full observability.
Qdrant
An open-source vector database written in Rust, built for low-latency similarity search at scale.
Qwen3-VL
Alibaba Qwen's open-weights vision-language model family (2B–235B, Apache-2.0): image and document understanding, OCR, visual reasoning, and video.
Replit Agent
Replit's AI agent that builds, runs, and deploys full-stack apps from a prompt inside the Replit cloud IDE.
Skyvern
Open-source vision + LLM browser automation aimed at replacing brittle RPA — workflow builder, CAPTCHA/2FA handling, and self-host or cloud.
Smithery
A registry and hosting platform for Model Context Protocol servers — discover, deploy, and connect MCP servers from one place.
