# litellm vs dify

litellm and dify share 5 technologies: Next.js, React, Flask, Redis, and Postgres. Both are written in Python.

- [BerriAI/litellm](https://seerepo.com/r/BerriAI/litellm): The fastest, litest AI Gateway. Rust core with Python SDK. Call 100+ LLM APIs in OpenAI (or native) format with cost tracking, guardrails, load balancing, and logging [Bedrock, Azure, OpenAI, Anthropic, OpenAI, VertexAI, vLLM, Nvidia NIM]
- [langgenius/dify](https://seerepo.com/r/langgenius/dify): Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace. Deploy on cloud, VPC, or self-hosted, so teams move from prototype to production without rebuilding the stack.

## What they share and what sets them apart

- In common: Next.js, React, Flask, Redis, Postgres
- Only in litellm: FastAPI, axum, OpenAI, Claude, Anthropic
- Only in dify: net/http, Sentry, Resend

## Side by side

| | litellm | dify |

| Size | 4,405,837 lines written, 5,630 code files | 2,251,379 lines written, 6,491 code files |
| Who writes it | 20% of its commits signed by AI. With Claude Code, Devin, Cursor, GitHub Copilot, OpenHands, Codex, Aider, and Gemini CLI | 5.1% of its commits signed by AI. With GitHub Copilot, Claude Code, Gemini CLI, Codex, Jules, Devin, Cursor, and Warp |
| Activity | Last push October 30, 2026, 45,956 commits, 62,405 stars | Last push October 29, 2026, 14,589 commits, 159,891 stars |
| Tests | 6,741 test files. 21.7% of its code files have a test that imports them | 4,495 test files. 65.5% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
