Most buyers should pick SigNoz.
SigNoz is the better fit for developers who want an OpenTelemetry-native observability stack, self-hosting, and published usage rates for logs, traces, and metrics. Datadog is a broader platform covering observability, security, digital experience, and software delivery, but the published pricing here covers AI Credits rather than its full platform. Compare your expected ingestion, deployment requirements, and need for security or delivery features before choosing; confirm API and SDK details against each vendor’s documentation.

02Pricing at real usage
SigNoz has a free, self-hosted Community edition. Its Teams plan has a $49 monthly minimum, including $49 of usage; additional logs and traces cost $0.30/GB, and metrics cost $0.10 per million samples. Eligible startups can pay $19/month for the first 12 months, including $19 of telemetry usage. Enterprise starts at $4,000/month, with up to $4,000 in monthly ingestion usage for Dedicated Cloud.
Datadog’s published figure here is for AI Credits, not its full observability platform: 500 credits cost $500/month when billed annually, or $1.30 per credit on-demand. The credits include Bits Chat, Bits Investigation, and Bits Code. These prices are not directly comparable to SigNoz ingestion rates. Before committing, estimate telemetry volume for SigNoz and ask Datadog for a quote covering the products and usage your stack needs.
03API, SDKs and integration
SigNoz is OpenTelemetry-native. Its homepage describes using open standards instead of vendor SDKs, and its query options include a query builder, PromQL, and ClickHouse SQL. The documentation index is available through llms.txt, and the site says Markdown versions can be reached by appending .md to documentation URLs. It lists integrations including AWS, Azure, Google Cloud, Kubernetes, Slack, PagerDuty, and webhooks.
Datadog lists OpenTelemetry among its integrations, alongside AWS, Azure, Google Cloud, Kubernetes, OpenAI, and SAP. Its platform spans infrastructure, applications, logs, security, digital experience, and software delivery. The product pages referenced here do not identify exact API endpoints, SDK packages, supported programming languages, or CLI commands. Check the relevant vendor documentation for those details, plus authentication, quotas, and instrumentation coverage, before designing an integration. SigNoz’s OpenTelemetry approach gives teams a clear instrumentation path; Datadog offers a broader product surface to connect.
04Open source, self-hosting and lock-in
SigNoz offers an open-source Community edition that teams can self-host and manage. Its paid options also include Cloud, BYOC, and self-hosted deployments at Enterprise level. The site describes OpenTelemetry as a way to keep instrumentation portable as a stack changes. That can reduce dependence on vendor-specific instrumentation, though it does not by itself guarantee that stored telemetry, dashboards, alerts, or queries migrate unchanged. Check the repository’s licence and plan-specific terms before adopting it.
Datadog is presented as an integrated platform, and its homepage lists Bring Your Own Cloud Log Management; that is not the same as a self-hosted edition of the full platform. Datadog also lists an OpenTelemetry integration, but teams should confirm export formats and migration support for their specific products. If data portability is a requirement, verify how to export telemetry and configuration before rollout.
Questions people ask
Is SigNoz cheaper than Datadog?
SigNoz publishes a $49 monthly minimum for Teams, with rates for additional logs, traces, and metrics. Datadog’s listed $500 price is for AI Credits, not its complete observability platform. Compare a Datadog quote against your expected SigNoz ingestion and the specific products you need.
Can I self-host SigNoz or Datadog?
SigNoz offers a self-hosted Community edition and lists self-hosted, Cloud, and BYOC options for Enterprise. Datadog lists Bring Your Own Cloud Log Management, but not a self-hosted version of its full platform. Confirm deployment scope and operational responsibilities with each vendor.
Do both platforms support OpenTelemetry?
Yes. SigNoz describes itself as OpenTelemetry-native and frames open standards as a way to keep instrumentation portable. Datadog lists OpenTelemetry as an integration. Check each platform’s documentation for language-specific instrumentation, configuration, and supported signal details before implementation.
Which platform is better for a small team?
SigNoz is a stronger starting point if a small team wants a free self-hosted edition or a published $49 Teams minimum. Datadog may fit better when the team needs its wider set of security, digital experience, and software delivery products. Compare the full Datadog quote with your required scope.
