Our verdict on Baselime

Baselime is a cloud observability platform for developers and teams operating distributed and serverless applications. It combines logs, metrics, distributed tracing, error tracking, dashboards, alerts, and observability-as-code workflows. OpenTelemetry instrumentation and ingestion support make it a fit for modern web stacks, while integrations and deployment paths cover AWS, Cloudflare, Vercel, Next.js, Kubernetes, Slack, and GitHub. Teams looking for a free cloud service to investigate traces, logs, and errors in one workspace are the clearest audience.

Tracing is the product's central strength. Users can visualize distributed traces, analyze spans, correlate traces with logs, search telemetry using full-text search, and inspect downstream effects. Real-time error tracking and custom alerts based on trace-derived metrics extend the workflow beyond individual investigations. Custom dashboards provide a way to organize recurring views, while observability as code supports Terraform, AWS CDK, CloudFormation, and SST. These capabilities make Baselime particularly relevant to teams managing serverless or distributed systems through code and cloud services.

The Free plan costs 0 USD per month and includes up to 1B events per month, unlimited seats, unlimited environments, unlimited alerts, 7-day data retention, and no credit card requirement. That makes the entry point straightforward for teams evaluating cloud tracing without a paid commitment. The short retention window is a practical constraint for investigations that require older telemetry, and cloud deployment will not suit every operating model. Choose Baselime for free OpenTelemetry-based cloud observability; consider another tool if longer retention or a different deployment model is essential.
