Storage as software: programmable, decentralized data infrastructure
Define privacy, encryption, replication and reliability rules per dataset so storage behavior follows your specification instead of a provider's defaults.
Spread data across several cloud providers or self-hosted nodes from one control surface, reducing single-vendor dependency.
Tailor encryption and access strategies to each application's data sensitivity, keeping sensitive workloads isolated without separate tooling.
Regulatory requirements are modeled as first-class storage settings, helping teams document and enforce data-handling policy.

Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.

#1
The environments frontier AI trains on, and the agents that do the recurring work

Free / Open-sourceProvides deep production LLM observability and tracing, focusing heavily on debugging production failures and drift.
The multimodal data layer for computer vision and physical AI teams

SpecialistFeatures simulation and guardrail tools for testing LLM safety and robustness before production deployment.

Free / Open-sourceOffers robust LLM evaluation and testing suites with integrated enterprise gateways, prioritizing prompt benchmarking.

Focuses specifically on prompt versioning, collaborative CMS management, and agent tracing rather than general MLOps.

Specializes in automated LLM unit testing and security red-teaming, though less focused on traditional MLOps experiment tracking.

Blockchain AI suite for crypto research, smart contracts, and Web3 automation

Decision infrastructure for governed enterprise AI agents

Free / Open-sourceProvides an open-source workspace specifically for prompt experimentation, LLM evaluation, and agent deployment pipelines.
