Agentic Index
Langwatch vs Maxim Ai (2026)
Both score 6.5 of 14 and both simulate agents before production, which few others in this cluster do.
LangWatch is open source and self hostable with scenario based simulation, OpenTelemetry tracing and a built in AI gateway, free cloud to 200,000 events. Maxim covers simulate, evaluate and observe across the lifecycle with a gateway reaching more than a thousand models, from 29 dollars per seat with a free developer tier. LangWatch is the open option; Maxim's thousand model gateway is the broader routing layer.
Choose Langwatch if
- Open source self hosting is a requirement.
- OpenTelemetry native tracing fits the observability standard you already use.
- A free cloud tier to 200,000 events is generous enough to evaluate properly.
Choose Maxim Ai if
- A gateway to a thousand plus models is routing breadth you would actually use.
- Per seat pricing at 29 dollars is predictable as the team grows.
- Lifecycle coverage from simulation through production observation in one tool.
