Microsoft has shipped version 1.0 of its Agent Framework for .NET and Python — a production-grade SDK for building multi-agent systems that works across Azure OpenAI, OpenAI, Anthropic Claude, Amazon Bedrock, Google Gemini, and Ollama simultaneously. It's the company's attempt to be the neutral orchestration layer across the increasingly fragmented AI provider landscape. The framework ships with built-in MCP (Model Context Protocol) tool discovery and invocation, plus support for A2A (Agent-to-Agent) protocol for cross-runtime coordination between agents built on different frameworks. Orchestration patterns include sequential, concurrent, handoff, group chat, and Magentic-One (the multi-agent research pattern Microsoft published last year). There's also a Semantic Kernel integration path for teams already using that ecosystem. For enterprise teams that have been evaluating LangChain, CrewAI, LlamaIndex Workflows, or Autogen, Microsoft Agent Framework 1.0 positions itself as the 'boring infrastructure' choice — opinionated enough to ship fast, flexible enough to avoid vendor lock-in. The cross-provider MCP support in particular is notable: one tool definition, any model.

Plain is a full-stack Python web framework explicitly designed to work well with both human developers and AI agents. A fork of Django driven by ongoing development at PullApprove, it reimagines proven patterns for the agentic era: explicit, typed, predictable code that LLMs can understand, navigate, and modify without disambiguation. The framework ships with built-in agent tooling including rules files in '.claude/rules/' for guardrails and installable agent skills like '/plain-install', '/plain-upgrade', and '/plain-optimize'. The CLI unifies development into four commands: 'plain dev', 'plain fix', 'plain check', and 'plain test'. Thirty first-party packages cover authentication, analytics, payments, and more — reducing the assembly burden of a typical Django project. The tech stack is deliberately modern: PostgreSQL ORM with QuerySet API, Jinja2 templates, htmx and Tailwind CSS for frontend, Astral tools (uv, ruff, ty) for Python tooling, and oxc/esbuild for JavaScript. Python 3.13+ required. The design philosophy — prioritizing clarity and structure specifically to make code comprehensible to LLMs — reflects a bet that agentic-native frameworks will outperform retrofitted ones as AI-assisted development becomes the norm.

MCP support plus A2A out of the box is the combination I've been waiting for in an enterprise-friendly package. If your team is .NET-first, this is now the obvious choice — stop evaluating and start shipping.

80/100 · ship

A Django fork that actually makes the right tradeoffs for 2026: drops the legacy baggage, goes all-in on PostgreSQL and type annotations, and adds first-class agent tooling with Claude rules files and installable agent skills. The unified CLI ('plain dev', 'plain fix', 'plain check', 'plain test') is the kind of opinionated ergonomics that makes day-to-day development faster. If you're starting a new Python web project and want it to work well with Claude Code, Plain is worth evaluating seriously.

Skeptic
45/100 · skip

Another orchestration framework in a field that's already saturated. The 'works with everything' pitch usually means 'optimized for nothing' — and 1.0 software from Microsoft often means 'production-ready in 2027.' Wait for the ecosystem to mature.

45/100 · skip

Django has survived 20 years because its stability and ecosystem matter more than its legacy baggage. Plain has 30 first-party packages and one production deployment: PullApprove, the startup that built it. That's not a community, that's a well-maintained internal framework that got open-sourced. 'Designed for agents' is also a questionable differentiator — Django apps work fine with Claude Code because LLMs read Python, not because the framework has agent-native features. The rules files in .claude/rules/ are just advisory text, same as CLAUDE.md.

Futurist
80/100 · ship

A2A protocol support across runtimes is the infrastructure play that matters here. If agents from different frameworks can coordinate natively, the fragmentation problem in multi-agent systems essentially disappears — Microsoft may have just defined the standard.

80/100 · ship

The design philosophy — explicit, typed, predictable code that machines can understand and modify — points to a real insight: the frameworks we write code in will increasingly be co-designed with AI agents as first-class users. Plain is early proof that 'agentic-native' is a legitimate axis for framework design, not just a marketing adjective. Expect other frameworks to adopt similar agent tooling within two years.

Creator
45/100 · skip

Not really a creator tool, but as a solo builder who occasionally glues agent workflows together — the provider-agnostic approach is appealing. I'll revisit once the community has stress-tested it.

80/100 · ship

For indie hackers building SaaS products with AI assistance, a framework built to be understandable by both you and your coding agent reduces the friction of the 'explain this codebase to Claude' step. The 30 first-party packages covering auth to analytics mean you're not assembling Django plugins from six different maintainers.
