Rookout is a technology company.
Rookout provides a live debugging platform, enabling developers to retrieve real-time, code-level data directly from running applications. It allows dynamic placement of non-breaking breakpoints in production and other environments, eliminating the need for code changes or application restarts. This capability streamlines troubleshooting and understanding application behavior within cloud-native and Kubernetes systems.
Founded in 2017 by Liran Haimovitch and Or Weis, Rookout emerged from their direct experience with developers' significant challenges in debugging and understanding code within live operational settings. This insight highlighted the critical need for an efficient, non-intrusive method for engineers to access diagnostic data from their applications.
Rookout’s platform targets development and engineering teams optimizing debugging workflows and expediting issue resolution. The company envisions making debugging effortless and rapid, directly enhancing developer productivity and minimizing time spent on application maintenance. It aims for engineers to gain deep insights into their code’s performance across all environments.
Rookout has raised $28.0M across 3 funding rounds.

Rookout is a developer-first observability platform that provides live debugging and data collection tools, enabling engineers to troubleshoot production code 5x faster without redeploying, restarting apps, or adding code[1][3]. It serves software development teams at enterprises with hybrid cloud architectures, solving the core problem of limited visibility into complex, distributed applications—from cloud-native and serverless to on-prem environments—by delivering real-time code-level insights across languages like Java, Node.js, Python, .NET, Ruby, and Go[1][2][3][6]. Rookout's growth culminated in its acquisition by Dynatrace in 2024, integrating its capabilities into a leading unified observability platform to enhance developer productivity and shift-left/right observability practices[4].
Rookout was co-founded by CTO Liran Haimovitch and CEO Or Weis, with Shahar Fogel later serving as CEO, emerging from the need to address observability gaps in modern, complex application architectures despite technological advances[1][2][4]. The idea stemmed from developers' persistent challenges in gaining real-time insights into remote, distributed code—especially in production, serverless, and Electron apps—without cumbersome logging or reproduction efforts, as highlighted by founders' comments on debugging diverse end-user environments like hospital networks[1][2]. Early traction built on its innovative real-time instrumentation, supporting key languages (Python, JVM, Node.js) and all cloud environments, positioning it as a pioneer in live metrics, front-end debugging, and cost-saving logging[1][2].
Rookout stands out through these key strengths:
Rookout rides the shift-left/right observability trend, where developers integrate testing, quality, and security directly into code and production amid rising microservices, Kubernetes, and serverless complexity[4]. Its timing aligns with exploding cloud-native adoption, where traditional logging fails due to volume and distribution, enabling faster MTTR (mean time to resolution) in agile cycles[1][3]. Market forces like AI-driven automation demands and cost pressures on logging favor Rookout's surgical, on-demand data collection, influencing the ecosystem by setting standards for developer observability—now amplified via Dynatrace's platform, which serves thousands of enterprises[4].
Post-acquisition, Rookout's tech will fuse with Dynatrace's AI and automation to redefine production debugging, slashing maintenance time and boosting feature velocity for dev teams[4]. Trends like AI-assisted coding, edge/serverless expansion, and zero-trust security will propel its evolution, potentially extending to more languages/environments while emphasizing privacy-aware, governance-compliant tools. As cloud complexity grows, Rookout's influence could standardize "debug anywhere" practices, empowering developers to deliver higher-quality releases faster—transforming observability from reactive to proactive, much like it originally disrupted debugging for hybrid worlds[1][3][4].
Rookout has raised $28.0M in total across 3 funding rounds.
