Open-weight foundation models built for agentic software engineering
- From
- $0.06/month
- Rated
- -
The short version
- Only LangGraph has a free tier, so it costs nothing to try first.
- Each has a real cost: LangGraph steeper learning curve compared to high-level abstractions; Poolside no self-serve public application; access is largely through enterprise sales or third-party model gateways
- They diverge on capability: LangGraph covers Human-in-the-loop controls, Poolside covers Laguna S 2.1.
- Prices and features above were last checked on 29 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
LangGraph
- Steeper learning curve compared to high-level abstractions
- Requires understanding of graph-based architecture
- Debugging complex workflows can be challenging
- Not optimized for simple, one-off use cases
Poolside
- No self-serve public application; access is largely through enterprise sales or third-party model gateways
- Pricing for the flagship enterprise and government offering is not public and requires a sales conversation
- Targets organizations with large (5,000+) developer headcounts, making it a poor fit for individuals or small teams
- Documentation and product surface area are thin compared to consumer-facing coding assistants
