CLI Proxy API

Anthropic API is the cloud API provided by Anthropic, the AI research company, offering programmatic access to its Claude family of large language models for text generation, chat, and reasoning. The API is intended for developers to integrate Anthropic's models into applications and services.

FreeLLMAPI is an open-source proxy that aggregates free tiers from multiple LLM providers behind a single OpenAI-compatible `/v1` endpoint. It can also connect custom OpenAI-compatible chat, embedding, image, and audio endpoints, including local servers and remote gateways. Its router selects an available model, fails over when a provider is rate-limited, stores provider keys encrypted, and tracks per-key usage against free-tier limits. The router refreshes its model catalog from a signed feed; free installations receive periodic snapshots, while the hosted premium offering provides the live catalog. The project is intended for personal experimentation and is available as a self-hosted install with a hosted service at freellmapi.co.

Free Claude Code is an independent open-source local proxy for routing Claude Code, Codex, Pi, OpenCode, and other coding-agent requests to selected free, paid, subscription, or local model providers while preserving their existing APIs. It provides a searchable model catalog and an Admin UI for configuring providers, supports automatic fallback to another configured model after provider retries are exhausted, and can be launched from a terminal, desktop app, IDE, Discord, Telegram, or phone. Optional RTK filtering reduces common terminal-output tokens, while voice input can use local Whisper or NVIDIA NIM transcription. The project states that it is not affiliated with or endorsed by Anthropic, and that provider free-tier availability and limits may change.

LiteLLM is an open-source AI gateway and Python SDK from BerriAI for calling more than 100 LLM providers through a unified OpenAI-compatible interface. It supports direct library integration and a self-hosted proxy server, with provider-specific formats translated into common endpoints such as chat completions, responses, embeddings, image generation, audio, batches, reranking, messages, and agent-to-agent calls. The proxy provides centralized authentication and authorization, virtual keys, per-project and per-user spend tracking, logging, guardrails, caching, load balancing, routing with retry and fallback logic, and an administration dashboard. LiteLLM also exposes MCP tools and A2A agents through the gateway and can be deployed as a componentized stack with separate gateway, backend, and UI services. The repository describes it as open source and documents Docker, local development, and Terraform deployment options for AWS and Google Cloud.

Docker MCP Gateway is an MCP gateway and Docker CLI plugin for configuring, running, and connecting MCP servers to AI clients. It routes requests between clients and MCP servers running in isolated Docker containers through a unified interface, allowing tools, resources, and prompts from multiple servers to be managed through one gateway endpoint. Servers are grouped into profiles that can be connected to clients, exported, shared through OCI registries, and configured with tool allowlists. The gateway supports stdio and streaming transports, dynamic tool and resource discovery, server lifecycle management, logging and call tracing, secrets management, and OAuth flows. It can run with Docker Desktop or independently, and the repository is licensed under the MIT License.
