UltraRAG
ultrarag.github.ioA low-code RAG development framework built on the Model Context Protocol, letting a developer assemble retrieval-augmented-generation pipelines from independent MCP servers and orchestrate them with YAML.
Coze Loop
github.comAn open-source edition of a developer platform for the full lifecycle of AI agents, covering prompt development, evaluation and observability.
Awesome Hermes Agent
nyk.devAn independent, curated directory of skills, plugins, memory providers, and surfaces for Hermes Agent, the open-source self-improving agent from Nous Research.
Gemma
gemma-llm.readthedocs.ioA JAX library for using and fine-tuning Gemma, Google DeepMind's family of open-weight large language models built on Gemini research.
pngquant
pngquant.orgA command-line PNG compressor that converts images to an efficient 8-bit palette format with alpha channel, typically shrinking files 60 to 80 percent, also available as an embeddable library.
Dograh AI
app.dograh.comA self-hostable, open-source alternative to Vapi and Retell for building voice AI agents with a visual workflow builder, letting a team bring their own LLM, speech-to-text and text-to-speech providers.
llama-swap
github.comA model-swapping proxy that runs multiple local AI models and hot-swaps between them on demand, working with any OpenAI or Anthropic API compatible server.
GPUStack
gpustack.aiAn open-source GPU cluster manager that configures and orchestrates inference engines such as vLLM and SGLang, and lets a team launch SSH-accessible GPU instances on demand.
Daft
daft.aiA high-performance data engine for AI and multimodal workloads that processes images, audio, video and structured data at scale, with built-in operations for running LLM prompts and generating embeddings.
Lemonade
lemonade-server.aiA local AI server that runs large language, speech and image-generation models on a user's own GPU or NPU, exposing OpenAI, Anthropic and Ollama-compatible APIs at no cost.
PySpur
pyspur.devA visual playground for building and iterating on agentic workflows, letting an AI engineer define test cases, build an agent in Python code or a UI, and deploy it as an API.
AgentScope Java
java.agentscope.ioA production-ready Java framework for building distributed, enterprise-grade AI agents, with an event system, tool-call permission gating, middleware, sandboxed workspaces and multi-agent orchestration.
Klavis AI
klavis.aiAn MCP integration platform offering prebuilt connectors, a context-optimizing tool router, and sandboxed MCP environments, so AI agents can use external tools reliably at scale.
AI Agent Deep Dive
github.comA research report on AI agent source code, distributed as downloadable PDFs, alongside a small teaching project that demonstrates how a minimal Python agent's core loop, tool skills and CLI fit together.
OpenResearch
openresearch.shA local-first workspace that turns coding agents such as Claude Code, Codex, OpenCode, Cursor or Google Antigravity into research agents that review literature, develop hypotheses, run experiments and produce research artifacts.
rLLM
docs.rllm-project.comAn open-source framework for training language agents with reinforcement learning, letting a developer bring any agent harness and sandbox and switch training backends with one flag.
AgentOps
agentops.aiAn observability and devtool platform for AI agents, giving Python developers session replay, LLM cost tracking, and integrations with agent frameworks such as CrewAI, AutoGen and LangGraph.
A hands-on workshop that teaches developers to build a coding agent in Go, one step at a time, starting from a basic chatbot and adding file reading, command execution and code search.
Emdash
emdash.comA desktop app for running multiple AI coding agents in parallel, each in its own Git worktree, so a developer can compare diffs across agents and merge the result that works.
Nexent
modelengine-group.github.ioA zero-code platform for building production-grade AI agents that unifies tools, skills, memory and orchestration with built-in constraints and feedback loops, described in plain language rather than assembled with drag-and-drop.
OpenConnector
oomol.comAn open-source connector gateway that lets AI agents and applications reach more than a thousand SaaS providers and prebuilt actions through an SDK, CLI, MCP, HTTP or OpenAPI.
Shimmy
github.comA single-binary, OpenAI-API-compatible local inference server for GGUF models, built entirely in Rust on the project's own WebGPU transformer engine, Airframe.
PI-Desktop
pi-docs.aiuo.netA modular desktop workspace where AI coding agents, models, plugins and workflows live together, so a developer can extend it with panels, tools, MCP servers and background services.
Chronos
arxiv.orgA family of pretrained time series forecasting models offering zero-shot univariate, multivariate, and covariate-informed forecasting, deployable through AWS SageMaker or AutoGluon.
