Big-O Complexity Analyzer & Code Playground

Instant Big-O time & space analysis for coding problems on leetcode.com, plus a built-in code playground. Free; AI is optional.

Optimize your algorithm solutions with an interactive complexity estimator, offline script environment, and structured data structure roadmaps. This companion extension provides immediate on-page runtime analysis for algorithm practice pages to evaluate performance bounds. Review structural execution paths, understand worst-case scenario boundaries, and access local evaluation panels directly within your browser. CORE CAPABILITIES: • Integrated Problem Companion: Review algorithmic bounds using the keyboard shortcut Alt+Shift+A or the context button on supported platform interfaces. • Multi-File Script Sandbox: A built-in scratchpad for evaluation. Features multi-language syntax highlighting, multi-file code workspace imports, traditional IDE hotkeys, local execution runtime environments, and dual-window output configurations. • Interactive Learning Paths: Tracks 71 foundational algorithm categories (including sliding window and dynamic programming concepts) with clear conceptual explanations, visual step animations, and progress logging. • Built-in Developer Utilities: Includes 21 distinct local developer utilities such as structured formatters, token decoders, regex validation blocks, side-by-side text comparisons, and basic token generators. PRIVACY BY DESIGN PRINCIPLES: • Local First: Processing functions execute entirely within your local browser ecosystem. • Secure Storage: Configuration settings and operational history remain isolated within local browser storage profiles. • Independent Integration: The platform provides optional interfaces for user-provided custom access credentials to display advanced code-explanation insights. Data transfers safely directly to your chosen backend providers without intermediate logging. • Tracking Free: Contains zero third-party tracking cookies, user telemetry scripts, or embedded advertising panels. Accelerate technical preparation, analyze architectural bounds, and verify local code iterations cleanly with an efficient utility tool tailored for software development.
