# Polly vs agent-framework

Polly and agent-framework share 3 technologies: Microsoft.Extensions.Caching.Memory, System.Diagnostics.DiagnosticSource, and Microsoft.Extensions.Logging.Abstractions. Polly is written in C# and agent-framework in Python.

- [App-vNext/Polly](https://seerepo.com/r/App-vNext/Polly): Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+.
- [microsoft/agent-framework](https://seerepo.com/r/microsoft/agent-framework): A framework for building, orchestrating and deploying AI agents and multi-agent workflows with support for Python and .NET.

## What they share and what sets them apart

- In common: Microsoft.Extensions.Caching.Memory, System.Diagnostics.DiagnosticSource, Microsoft.Extensions.Logging.Abstractions
- Only in Polly: System.ValueTuple, Microsoft.Extensions.Options, System.ComponentModel.Annotations, Microsoft.Extensions.Logging.Console
- Only in agent-framework: ASP.NET Core, FastAPI, azure-cosmos, azure-search-documents, Microsoft.Extensions.VectorData.Abstractions, pgvector, psycopg, pymongo, Microsoft.Azure.Cosmos, MongoDB, Redis, Azure.Storage.Blobs, Postgres, DuckDB, mssql-python, oracledb, OpenAI, MCP, Anthropic, Mistral AI, Qdrant, Microsoft.Extensions.Hosting, uvicorn, AIOHTTP, React, Vite, Azure.Identity, Microsoft.Agents.CopilotStudio.Client, msal, a2a-sdk, agent-framework-core, azure-ai-inference, github-copilot-sdk, mem0ai, Microsoft.Extensions.AI.Abstractions, Microsoft.Extensions.AI.OpenAI, ModelContextProtocol, Azure.AI.Projects, agent-framework-openai, Microsoft.Extensions.AI, AGUI.Abstractions, Ollama, typesafe-sdk, AGUI.Server, Microsoft.ML.Tokenizers, filetype, Pydantic, msgspec, jsonschema, Aspire, azure-core, OpenTelemetry, Microsoft.Extensions.Logging, boto3, botocore, psutil, Tailwind CSS, class-variance-authority, next-themes, tailwind-merge, Radix UI, xyflow, Lucide

## Side by side

| | Polly | agent-framework |
|---|---|---|
| Size | 106,814 lines written, 379 code files | 1,111,813 lines written, 1,483 code files |
| Who writes it | 0.1% of its commits signed by AI. With GitHub Copilot | 27.7% of its commits signed by AI. With GitHub Copilot, Claude Code, Cursor, and Codex |
| Activity | Last push November 7, 2026, 2,845 commits, 14,253 stars | Last push November 8, 2026, 3,881 commits, 14,594 stars |
| Tests | 325 test files. 81.5% of its code files have a test that imports them | 1,113 test files. 68.2% 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.
