LLM Developer Tools

LangChain’s suite of products supports AI development

Run Llama 2 and other models on macOS, with Windows and Linux coming soon. Customize and create your own.

Google Labs is an experimental hub where Google publicly tests early-stage AI products and features. It includes projects like AI-powered search enhancements, Workspace integrations (e.g. Gmail and Docs assistants), and generative tools such as NotebookLM.

UTCP (Universal Tool Calling Protocol) is an open standard for AI agents to call tools directly, positioned as a lightweight alternative to MCP. It eliminates the "wrapper tax" for lower latency by using a simple JSON manifest to connect to native APIs.

Airbolt lets you securely call LLM APIs with zero backend. Just add our client SDK to your app and start making inference calls with best practices built in.

Supacrawler is a lightweight API for devs to reliably extract clean content from the web. Open source!

Features: Scrape — fetch cleaned content (rendered JS) from a URL. Crawl — follow links to crawl entire sites or sections. Screenshots — capture visual renderings of pages (full page, element, etc). Watch — Monitor website changes. Parse — submit a URL + prompt + a schema (optional) or desired format (JSON, CSV, YAML, MD), and it returns structured data without needing custom scraper logic.

Filer transforms file management with AI-powered semantic search and intelligent assistants. Search files by content, not names. Create custom AI assistants from your directories using RAG technology. Currently in beta - runs locally for privacy.

DoCoreAI is an open-source optimization engine that makes AI prompting data-driven instead of trial-and-error. Developers and teams can reduce costs, improve accuracy, and ship faster by dynamically tuning prompts.

With intelligent telemetry + optimization, DoCoreAI helps you track ROI, refine prompts systematically, and unlock reliable AI performance.

Open MLLM family (1B-78B) from OpenGVLab. Excels at vision, reasoning, long context & agents via native multimodal pre-training. Outperforms base LLMs on text tasks.

LLMs.txt Generator creates free llms.txt files for AI models like ChatGPT, Gemini, DeepSeek, Grok, Claude. Crawl sites, structure content, enhance AI discoverability

Adaptive cuts LLM costs by up to 90% while boosting response quality. Real-time routing, semantic caching, and automatic failover ensure cheaper, faster, more reliable inference, with zero setup and no vendor lock-in.

Stop scrolling through useless “New conversation” titles. GenAI Conversation Explorer lets you search across ChatGPT + Claude with real keywords, merge exports, and export clean subsets. 100% local + private, free, open-source.

Zylo is the world's best agent for making products without coding. Ships mobile apps, web, or both. Designs that don't look AI-made. Everything built in, no extra tools needed.
