The open-source APM and observability platform for engineering teams
SigNoz is a brilliant Indian startup actively disrupting the global Application Performance Monitoring (APM) market. Built natively on OpenTelemetry, it is the premier open-source alternative to Datadog. For scaling Indian engineering teams tired of being blindsided by massive Datadog bills, self-hosting SigNoz provides enterprise-grade observability (unifying logs, metrics, and traces) at an absolute fraction of the cost.
Quick facts: Founded in 2020 by Pranay Prateek and Ankit Nayan · Backed by $6.65M in total funding (including a major $5.4M round from SignalFire) · Uses a highly efficient ClickHouse storage backend.
While Product Managers obsess over user behavior tools like Mixpanel, Engineering teams obsess over Observability. When an Indian consumer opens a quick-commerce app on Diwali night and the "Checkout" button takes 8 agonizing seconds to load, the user drops off. The PM sees a dip in the conversion funnel, but they cannot fix it. The Engineering team must figure out why the app was slow. Was the Razorpay payment gateway API lagging? Was the Postgres database experiencing deadlocks? Did a microservice crash and restart?
Application Performance Monitoring (APM) tools answer these exact questions. Historically, legacy giants like Datadog and New Relic monopolized this space. However, their pricing is notoriously predatory—startups frequently wake up to $20,000 monthly bills because a junior engineer accidentally left "Debug Logging" turned on over a long weekend.
SigNoz fixes this. It is a full-stack, open-source APM tool built natively on OpenTelemetry. It unifies Traces, Metrics, and Logs into a single pane of glass. Because it is open-source, an Indian startup can deploy it inside their own AWS Mumbai region, ensuring strict RBI/data localization compliance and capping their costs solely to raw AWS compute charges.
SigNoz doesn't force proprietary tracking agents on you. You instrument your Go, Python, or Node.js code once using the global OpenTelemetry standard, preventing vendor lock-in.
If you see a latency spike in a metric chart, you can click it and instantly view the exact log files and request traces associated with that specific minute. No context switching.
Visually map exactly how long a request spent in the Auth Service versus the Payment Database. Flamegraphs instantly highlight the specific bottleneck in a microservice architecture.
Automatically captures and aggregates unhandled exceptions from your codebase, grouping similar errors together so on-call engineers aren't overwhelmed with thousands of identical alerts.
SigNoz uses ClickHouse (a blazing-fast columnar database). This makes querying massive volumes of log data incredibly fast and highly efficient on storage costs compared to ElasticSearch.
Build granular dashboards tracking exact P99 latency limits. Configure alerts to ping PagerDuty or Slack the second an API drops below acceptable performance thresholds.
SigNoz offers a highly disruptive pricing model that directly attacks Datadog's complex billing. Note: Converted at 1 USD = ₹84. Excludes 18% GST.
Indian startups from Seed to Series C with engineering teams operating modern microservice architectures (Kubernetes/Docker) who want to escape the vendor lock-in and extortionate pricing of legacy APM tools.
It is specifically excellent for Fintech, Healthtech, and AI companies. Because these sectors deal with highly sensitive data (PII or LLM prompt inputs), sending raw application logs to an external SaaS provider in the US is a massive security risk. Self-hosting SigNoz guarantees the data never leaves your VPC.
Who should NOT use it: Non-technical teams without DevOps resources. While the managed Cloud version is easy to set up, self-hosting the open-source version requires an engineer who understands Docker, Kubernetes, and ClickHouse maintenance.
The absolute global market leader. Possesses an unparalleled ecosystem of integrations and extreme polish, but their aggressive billing practices make it a terrifying line item on a startup's P&L.
Choose when: Budget is unlimited and you want zero-configuration integrations for every AWS service.The traditional DIY open-source method. While highly effective, stringing these three disparate tools together creates a massive maintenance burden. SigNoz effectively replaces this fractured stack.
Choose when: Your DevOps team already has deep expertise in managing Elasticsearch clusters.A legacy giant that recently pivoted to a more transparent user-based pricing model, though it still suffers from some interface bloat compared to modern challengers.
Choose when: You need deep legacy support for older monolithic architectures.Stop paying premium SaaS markups for basic server logs. Our DevOps architects can help you migrate your telemetry to a secure, self-hosted SigNoz instance on your own Indian AWS infrastructure.
