Hud's Runtime Code Sensor dynamically and automatically captures live function-level data from production, giving engineers and AI coding agents the missing context they need to detect and fix issues before they impact customers. Installed in seconds with zero configuration, Hud streams real-time code behavior directly into the development environment, enabling software teams to build with confidence in how their systems work in the real world.
Hud is the first Runtime Code Sensor designed to dynamically and automatically gather unique live service and function-level data straight from production. It gives software engineers and AI coding agents the missing context they need to detect and fix issues fast, and to build features that work in complex real-world environments.
No matter how carefully code is written, systems fail in surprising ways once deployed to production. Traditional observability tools only work in hindsight and require configuration to know where to look. Hud changes this. Installed in a minute and requiring zero maintenance, Hud captures exactly how code behaves in real-world conditions continuously and at scale.
Its core technology is a low-level software sensor built from first principles for AI-native development. It captures structured runtime metadata at the service and function level, optimized to provide the context LLMs and engineers need to understand performance, errors, and behavior in production. It is already running in millions of services across massive production environments with negligible overhead.
Engineering teams rely on Hud to:
Detect production issues before users are impacted
Pinpoint function-level root causes with real-time data
Understand how code behaves across deployments
Guide code-generating agents with accurate system context
Resolve incidents faster without relying on logs, traces, or dashboards
Hud brings this context directly into developer tools IDE extensions, agent integrations, and CI/CD pipelines closing the gap between code and reality. By giving teams continuous awareness of how their software behaves in production, Hud enables fast, confident shipping and reliable, production-safe code, whether written by humans or agents.
Highlights
Production-Aware Development: Hud brings real-time, function-level runtime data into the developer workflow giving engineers continuous insight into how their code behaves in the real world.
Enterprise Ready: Hud already runs in millions of services across high-scale production environments and is fully compliant with SOC2 Type II, ISO 27001, and GDPR.
Zero Configuration Monitoring: Hud installs in a minute with no agents, no dashboards, and no tuning automatically capturing live production behavior with negligible overhead.

You choose from three tiers that scale by capacity and retention. All tiers include a set number of users and concurrent services. As you move from Free Tier to Basic Tier to Pro Tier, the limits rise. Free Tier and Basic Tier cover 5 users and 10 concurrent services, differing mainly in functions per service. Pro Tier adds more users, more concurrent services, higher functions per service, and longer data history retention. Pick the tier matching your team size, workload volume, and how long you need to keep runtime data.
Top-of-mind questions for buyers
What counts as one "concurrent service" and one "function" for these tier limits?
A service is a running application the SDK auto-instruments, such as an HTTP API or async worker. A function is a user-defined code function within that service. Hud maps your codebase and counts these automatically. It ignores third-party code like installed packages, so those functions do not count toward your limit.
What happens if I add more users or services than my tier includes?
Each tier sets fixed limits on included users, concurrent services, and functions per service. To go beyond those limits, you move to a tier with higher capacity. Free Tier and Basic Tier cover 5 users and 10 concurrent services; Pro Tier covers 10 users and 20 concurrent services.
How long does each tier keep my collected runtime data before it is removed?
Data history retention sets how long Hud stores your function-level telemetry and call graph. Free Tier and Basic Tier retain 7 days of history. Pro Tier retains 30 days. After the retention window, older runtime data is no longer available for review.
