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.
Uptime monitoring, on-call and status pages in one calm tool
Web and HTTPS endpoint checks with status code, keyword, response time and certificate validation, plus ping, TCP port, DNS record and mail server monitors — checked every 30 seconds from four regions.
Branching escalation paths decide who is notified, where and when, so severe alerts page someone immediately while warnings can wait for working hours.
Page the on-call engineer by SMS or phone call with one-key acknowledgement, and run the whole incident from Slack with /incident declare.
Publish branded status pages that follow every incident update, available in six languages and matched to the visitor.
