DSPy vs Microsoft Agent Framework
Both are alternatives to LangChain. Here's how they stack up — verified facts, no spin.
Also searched as Microsoft Agent Framework vs DSPy — same comparison, one verdict.
DSPy keeps your data local by default and Microsoft Agent Framework keeps it in the vendor's cloud — for most teams that single fact decides it.
DSPy
Programming, not prompting — Stanford's optimizer-driven approach.
DSPy (MIT, from Stanford NLP, ~34k stars) replaces hand-tuned prompt strings with something closer to software engineering: you declare what a step takes in and produces (a Signature), compose modules, and let an optimizer compile the best prompts and few-shot examples against your own metric and data. When quality matters and you're tired of prompt whack-a-mole, DSPy turns the tuning into a reproducible build step. It's the most intellectually distinct alternative on this list.
Microsoft Agent Framework
Semantic Kernel + AutoGen, unified — the enterprise agent stack.
Microsoft's Agent Framework 1.0 (April 2026) merged Semantic Kernel's enterprise foundations with AutoGen's multi-agent orchestration into one MIT-licensed SDK for .NET and Python — session state, type safety, middleware, telemetry, and graph-based workflows out of the box. It's the natural LangChain alternative for enterprise teams (especially .NET shops and Azure environments) that want long-term-supported APIs and a vendor standing behind the framework.
Side by side
6 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

|---|---|---|
| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 88 | 80 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |
| Local-first data | Yes | No |

DSPy edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Weighing both against staying on LangChain? Is LangChain free? What it actually costs →
DSPy
Strengths
- +Optimizes prompts against your metric — reproducibly
- +Declarative modules stay stable as models change underneath
- +Research-grade ideas with a real production following
Trade-offs
- −A genuinely different mental model — real learning curve
- −Optimization runs cost tokens; needs a decent eval set
Microsoft Agent Framework
Strengths
- +Enterprise plumbing included: sessions, telemetry, middleware
- +First-class .NET as well as Python
- +Stable 1.0 APIs with Microsoft LTS backing
Trade-offs
- −Microsoft-governed direction; strong Azure gravity
- −Heavier than needed for small apps
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose DSPy
if your data should stay on machines you control, and optimizes prompts against your metric — reproducibly.
Choose Microsoft Agent Framework
if enterprise plumbing included: sessions, telemetry, middleware.
Neither, yet
if both carry a real cost you should weigh first — a genuinely different mental model — real learning curve, and microsoft-governed direction; strong Azure gravity. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
DSPy vs Microsoft Agent Framework — common questions
Is DSPy a better fit than Microsoft Agent Framework for llm & agent frameworks?
It depends on what you are optimising for, and the honest split is this: DSPy scores 88 to Microsoft Agent Framework's 80 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Microsoft Agent Framework earns its place on a different axis — enterprise plumbing included: sessions, telemetry, middleware. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
DSPy keeps its data local or in open formats, so leaving is an export rather than a negotiation. Microsoft Agent Framework is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host DSPy or Microsoft Agent Framework?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are DSPy and Microsoft Agent Framework both alternatives to LangChain?
Yes — both appear in our LangChain comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off LangChain and now choosing between the two replacements, which is a narrower and much easier question.
