Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Datadog

Application

AI ImpactApplication

Detects AI-assisted pull requests from coding assistants such as Claude Code, Cursor and GitHub Copilot and compares them on adoption, PR throughput, cycle time, change failure rate and daily cost per active user.

Bits ChatApplication

Conversational AI interface for querying Datadog metrics, logs, traces and monitors in natural language and generating dashboards and notebooks, accessible from Datadog, Slack or mobile.

GPU MonitoringApplication

Datadog's Infrastructure-family product for shared GPU fleets across cloud, on-prem and neocloud providers: it links device health, cost and performance to the workloads and teams using them, alerts on unmet GPU requests, thermal throttling and ECC/XID errors, forecasts GPU demand and recommends optimisations such as reclaiming GPUs held by zombie processes. The page markets alerting, forecasting and recommendations but does not name a model or AI mechanism behind them.

WatchdogApplication

Datadog's built-in AI engine: it continuously analyses metrics, traces and logs across the platform to raise anomaly alerts without configuration, detect faulty deployments by comparing code versions, run automated root-cause analysis on critical failures and surface tag-based insights and impact analysis. Available inside Infrastructure Monitoring, APM, Log Management and RUM rather than sold on its own.

Developer tool

Agent ObservabilityDeveloper tool

Traces, evaluates and monitors LLM and AI-agent applications in production, with offline experimentation on datasets built from real traces.

Datadog MCP ServerDeveloper tool

Model Context Protocol server that gives AI coding agents such as Claude Code, Cursor and Codex secure real-time access to Datadog logs, metrics and traces under existing RBAC controls.

Fiddler AI

Application

Fiddler AI Governance, Risk Management, and ComplianceApplication

Governance module within the Fiddler AI Control Plane providing model inventories, policy enforcement and audit-ready reporting for regulatory compliance (e.g. EU AI Act) across an organization's AI systems.

Fiddler Agentic ObservabilityApplication

Tracing and monitoring module for multi-step agent workflows within the Fiddler AI Control Plane, tracking tool calls, reasoning steps and failures across an agent's execution.

Fiddler Continuous EvaluationsApplication

Ongoing automated evaluation module within the Fiddler AI Control Plane that re-scores production LLM/agent outputs against quality and safety metrics over time, not just at launch.

Fiddler GuardrailsApplication

Runtime safety layer within the Fiddler AI Control Plane that screens LLM/agent inputs and outputs for hallucination, toxicity, PII and jailbreak attempts before they reach users.

Developer tool

Fiddler AuditorDeveloper tool

Source-available library for red-teaming and robustness testing of LLMs, run independently of the hosted Fiddler platform. Fiddler's own page calls it "open-source"; its repository's actual licence is the Elastic License 2.0, which is not an OSI-approved open-source licence (it restricts offering the software as a competing hosted service), so it is recorded here by its real terms rather than the vendor's label.

No counterpart

Datadog sells these in a stack layer with no product recorded for Fiddler AI yet — nothing on the other side to compare them against.

AI agent

Bits CodeAI agent

Coding agent that triages production errors, regressions and vulnerabilities from Datadog telemetry, generates fixes with unit tests grounded in logs, traces and runtime variables, and opens pull requests for review.

Bits InvestigationAI agent

AI SRE agent that autonomously investigates every alert the moment it fires, explores multiple root-cause hypotheses in parallel and reports findings into Slack, Jira, ServiceNow or GitHub.

Bits Security AnalystAI agent

Always-on AI SOC analyst that autonomously triages and investigates security alerts and delivers written investigation results to Datadog, Slack or Jira within minutes.

Agent platform

Bits Agent BuilderAgent platform

No-code builder for custom AI agents that investigate, decide and act inside Datadog to automate incident response, observability, security and operational workflows.

Fiddler AI sells these in a stack layer with no product recorded for Datadog yet — nothing on the other side to compare them against.

Platform

Fiddler AIPlatform

AI observability platform: evaluation, monitoring and real-time guardrails for ML models and generative AI/agentic applications in production.
