smolagents alternatives
4 substitutes · 4 in agents · 0 adjacent
The short answer
4 tools on this index are recorded as a substitute for smolagents. 4 of these run the same way you already deploy smolagents (self-hosted), and 3 are permissively licensed, so they do not change what you can ship. All of them sit in Agent Frameworks, so the choice is a real one rather than a category change. There is no overall winner here: which one is right depends on traffic shape, operational budget and how much of smolagents you have already built around.

in Agent Frameworks- Pydantic AIframework · MIT
Type-safe agent framework that leans on Pydantic models.
Use when Type-safe agents where schema correctness is the priority.
Skip when You want a batteries-included ecosystem.
- OpenAI Agents SDKframework · Apache-2.0
Lightweight primitives for handoffs, guardrails and tracing.
Use when A small, legible set of primitives for handoffs and guardrails.
Skip when You need multi-provider abstraction at every layer.
- Agnoframework · MPL-2.0
Minimal agent runtime centered on model-agnostic tool interfaces.
Use when A minimal agent runtime with model-agnostic tool interfaces.
Skip when You need the wider ecosystem around it.
- Lettaplatform · Apache-2.0
Agent runtime with persistent, editable memory as a first-class primitive.
Use when Agents whose memory is a first-class, inspectable and editable state.
Skip when You want memory to be a detail the framework handles for you.
This graph is bidirectional and unsponsored. A tool appears here if smolagents or another entry names it as a substitute, and Pydantic AI, OpenAI Agents SDK, Agno and Letta point at smolagents as well. How this index is compiled — including where it is wrong.
