Bentoml
Open-source platform for building, shipping, and managing machine learning models.
The go-to open-source framework for MLOps teams deploying model inference to production; Modular Cloud adds managed scale at usage-based rates.
BentoML — open-source ML model serving framework; managed cloud now under Modular (acquired Feb 2026).
BentoML is the leading open-source framework for packaging and deploying ML models as production-grade REST APIs, supporting any framework (PyTorch, TensorFlow, ONNX) with auto-scaling, dynamic batching, and multi-model pipelines. The managed cloud offering (BentoCloud) was acquired by Modular in February 2026 and now operates as Modular Cloud. DB pricing is partially correct — freemium accurately captures the free OSS tier, but 'Custom' misrepresents the cloud tier, which is usage-based (per token or per GPU minute), not quote-driven.
The open-source framework eliminates vendor lock-in for model serving — teams self-host any model with production-grade tooling at no cost, then optionally migrate to managed cloud as scale demands.
Cloud pricing (now under Modular post-acquisition) requires a separate Modular account; BentoCloud brand is being absorbed into Modular, creating short-term documentation fragmentation for existing users.
