Rookout offers a developer-first observability platform focused on giving engineers live visibility into their code in production via dynamic instrumentation and “non-breaking breakpoints.” Its core features enable live debugging and the collection of runtime data, and the product integrates tracing standards like OpenTracing and OpenTelemetry as well as third-party logging services. The company emphasizes developer ownership of production behavior and supports workflows that surface business logic rather than just infrastructure metrics. Customers include Amdocs, Cisco, Dynatrace, Jobvite, Santander Bank and UPS. The team is relatively small (the article references 20 engineers) and the company says it has seen its revenue grow 20x since its last funding round in 2019. Rookout is positioning to scale its developer-focused observability offering and expand further into enterprise accounts. Rookout offers a production debugging platform that collects code-level data on demand without redeploying, supporting serverless (including AWS Lambda), containers, Kubernetes, and PaaS like Google App Engine and Elastic Beanstalk. The company emphasizes visibility into ephemeral platforms that are traditionally hard to observe. Over the past year customers have found new uses for Rookout’s code-level data collection capabilities, prompting the company to expand beyond pure debugging. Rookout plans to use its latest funding to broaden support and enhance its observability and pipelining features. The startup launched in 2017 and maintains offices in San Francisco and Tel Aviv. It has a team of about 20 employees and has raised more than $12 million to date. Rookout builds debugging tools for applications that run on modern container and serverless platforms. The company launched a live Kubernetes debugger feature that brings the equivalent of breakpoints to Kubernetes. Rather than stopping code execution, Rookout collects full-stack data so developers can inspect variable state with a few clicks. That design allows use in both development and production environments and aims to reduce reliance on complex logging and distributed tracing setups. CTO and co-founder Liran Haimovitch said the product restores the breakpoint-like visibility developers and DevOps need without halting apps. The company has raised $4.2M for its rapid production debugging platform.
