# adk-python vs hindsight

adk-python and hindsight share 7 technologies: FastAPI, Google, uvicorn, cryptography, Pydantic, opentelemetry-api, and OpenTelemetry. Both are written in Python.

- [google/adk-python](https://seerepo.com/r/google/adk-python): An open-source, code-first Python toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.
- [vectorize-io/hindsight](https://seerepo.com/r/vectorize-io/hindsight): Hindsight: Agent Memory That Learns

## What they share and what sets them apart

- In common: FastAPI, Google, uvicorn, cryptography, Pydantic, opentelemetry-api, OpenTelemetry
- Only in adk-python: aiosqlite, SQLite, starlette, google-auth, authlib, jsonschema
- Only in hindsight: pgvector, psycopg2-binary, Postgres, Claude, OpenAI, AIOHTTP, fastmcp, Tokio, Next.js, React, Preact, Rich, crossterm, indicatif, Ratatui, SQLAlchemy, alembic, pyjwt, einops, Haystack, openai-agents, pydantic-ai-slim, strands-agents, litellm, torch, CrewAI, google-adk, LangChain, llama-index-core, autogen-core, MCP, pillow, validator.v2, opentelemetry-semantic-conventions, opentelemetry-exporter-otlp-proto-http, opentelemetry-instrumentation-fastapi, Tailwind CSS, class-variance-authority, @tailwindcss/postcss, PostCSS, next-themes, tailwind-merge, sonner, Radix UI, react18-json-view, recharts, cmdk, Lucide, react-markdown, remark-gfm, ai, Zod, @opencode-ai/plugin, js-yaml, @clack/prompts

## Side by side

| | adk-python | hindsight |
|---|---|---|
| Size | 811,720 lines written, 932 code files | 749,226 lines written, 1,156 code files |
| Who writes it | 0% of its commits signed by AI. With Gemini CLI and Jules | 6.8% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 5, 2026, 5,111 commits, 22,107 stars | Last push November 5, 2026, 4,037 commits, 58,979 stars |
| Tests | 864 test files. 74.4% of its code files have a test that imports them | 1,333 test files. 30.2% 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.
