## Datadog

Datadog began as a hosted infrastructure-monitoring service and has grown into a broad platform spanning observability, application security, digital experience and service management. Its core promise is a single, consistent data model: metrics from agents and cloud integrations, distributed traces from instrumented services, logs from collectors, real user monitoring from browsers and mobile apps, and synthetic checks from managed locations all land in the same graph, so a spike in latency can be tied to a specific deploy, container, database query or error log without switching consoles.

On top of that foundation, Datadog layers AI-assisted workflows. Bits AI acts as an investigation and chat assistant, an agent builder lets teams compose automation, and dedicated AI Observability and LLM monitoring views track model latency, cost, token usage and agent traces. Security surfaces such as Cloud SIEM, Cloud Security Posture Management, vulnerability management and code scanning share the same telemetry, and software-delivery features cover CI visibility, test optimization, feature flags and DORA metrics.

Datadog is aimed at teams running cloud-native, multi-cloud and Kubernetes-heavy estates, from startups to large enterprises. It is a paid, usage-metered service with a free trial and generous free allowances on many individual products, and it ships official SDKs, an MCP server, OpenTelemetry support and an integrations directory covering AWS, Azure, Google Cloud, databases, queues and popular frameworks.

**Pricing & Plans:** Usage-based SaaS pricing. New customers get a free trial, and many individual products include free tiers or allowances (for example, a handful of free hosts, limited custom metrics or log ingestion credits). Beyond that you pay per host, per ingested log volume, per indexed span, per monitored synthetic test and per security seat, with annual commitments typically discounted. Enterprise and consolidated-bundle plans are quoted by sales.

- **Unified metrics, traces and logs:** Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
- **AI-assisted investigation:** Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
- **Security in the same data model:** Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
- **Digital experience and delivery:** Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.
- **Alerting, SLOs and automation:** Metric, log and trace monitors, service-level objectives, event management, on-call schedules and workflow automation turn signals into coordinated action.

**Strengths:** Very broad product coverage from infrastructure, APM and logs through to security, RUM and software delivery; Strong integrations and OpenTelemetry support across clouds, runtimes and languages; Shared data model makes cross-signal correlation practical in one interface; Reliable alerting, dashboards, SLOs and collaboration features for on-call teams

**Limitations:** Costs can climb quickly because pricing is granular per host, per log volume and per span; The breadth of the catalogue means onboarding and configuration take real effort; Some advanced AI and security modules require separate purchases, which complicates budgeting

## Rerun

Rerun is an open-source SDK and visualizer built for multi-rate, multimodal data, and it markets itself as the data layer for physical AI. Engineers use it to log sensor streams, computer-vision outputs, 3D transforms, and time-series metrics from the first recording through to large-scale review. Because it is a flexible framework rather than a locked platform, teams can extend the viewer with their own views and tools at each stage of the pipeline.

The SDK ships with Python, Rust, and C++ APIs, so it fits into existing robotics and perception stacks without a rewrite. Data is stored as column-chunks in rrd files, which supports full dataframe or SQL queries over any recording, down into the columns, time ranges, and values inside it rather than only metadata.

Beyond the free tooling, Rerun offers Rerun Hub, a production backend that catalogs recordings, indexes byte ranges, and turns object stores into a queryable, streamable foundation. Hub supports running transforms on the edge or close to the data and streaming datasets directly to GPUs for training without an export step.

**Pricing & Plans:** The Rerun SDK and viewer are open source and free to use. Rerun also offers Rerun Hub, a production backend, whose pricing is arranged separately with the team. Check the Rerun website and GitHub repository for current terms.

- **Multimodal data visualization:** Log, store, and view images, point clouds, 3D transforms, and time series together in one viewer.
- **Open-source logging SDK:** Record multi-rate, multimodal data as column-chunks in rrd files, or convert from other formats.
- **Query and transform:** Run full dataframe or SQL queries over robotics data, down into columns, time ranges, and values.
- **Edge and stream transforms:** Add derived columns and evolve schemas without breaking history, on the edge or near the data.
- **Rerun Hub backend:** A hosted backend with catalog, byte-range indexing, and retrieval that turns object stores into a queryable dataset.

**Strengths:** Open-source core with permissive use across research and production; Handles multimodal and multi-rate data in one viewer; APIs for Python, Rust, and C++; Query and transform data without an export step

**Limitations:** Requires coding in Rust, Python, or C++ to get full value; The hosted Rerun Hub backend is a newer, additional product beyond the free SDK; Visualization work is aimed at engineering teams, not general business users; Advanced production features assume existing logging pipelines
