Free algorithm visualization platform from National University of Singapore (NUS) covering 26+ data structures and algorithms. Provides step-by-step animated visualizations for sorting algorithms (Quick Sort, Merge Sort, Heap Sort), graph algorithms (Dijkstra, BFS, DFS, Kruskal, Prim), tree structures (BST, AVL, Red-Black, Segment Tree), and dynamic programming problems. Used by 2M+ computer science students globally for exam preparation (CS1020, CS2040, CS3230), coding interview prep (FAANG companies), and algorithm complexity analysis (Big-O notation). Each visualization includes pseudocode, time complexity breakdown, and interactive mode for custom input. Created by Dr. Steven Halim and maintained by NUS School of Computing. Alternative to Algorithm Visualizer, USFCA Visualization Tool, and Sorting.at.

Revieko is an architecture drift radar for codebases that learns an architectural baseline from your repository and reviews every change against that baseline inside pull requests. It highlights where the architecture starts to diverge over time with a drift risk score, the most impacted areas (hotspots), and concrete signals you can act on during review. Designed to prevent architectural erosion, keep module boundaries meaningful, and reduce the hidden cost of small PRs accumulating into big structural debt.

Cursor is an AI-first code editor built on VS Code, featuring AI chat, codebase understanding, multi-file editing, and inline generation. Using GPT-5.2 and Claude models, it enables natural language programming, refactoring suggestions, bug fixes, and documentation generation, accelerating development with context-aware AI assistance integrated directly into the workflow.

SonarQube is a code quality and security platform built for development teams that rely on AI-generated code. It runs static analysis across 40+ languages, catches bugs, security vulnerabilities, and code smells before they reach production, and integrates directly into CI/CD pipelines and pull request workflows. Quality gates automatically block merges when new code fails defined thresholds for coverage, duplication, or security issues. The AI CodeFix feature generates one-click remediation suggestions using LLMs, while AI Code Assurance validates that AI-generated code meets the same quality and security standards as human-written code. Over 7 million developers across 500,000 organizations use SonarQube, including Mercedes-Benz, Adobe, NVIDIA, NASA, and Pfizer. Available as SonarQube Cloud (managed SaaS, SOC 2 Type II certified) or SonarQube Server (self-hosted, air-gapped options). The Team plan starts at $32/month with a 14-day free trial.

Windsurf is a groundbreaking agentic IDE that merges copilot and agent functionalities, allowing developers to engage in autonomous coding workflows. Its innovative approach minimizes interruptions and boosts productivity through intelligent automation, ensuring creators stay in their optimal flow state.

Junction is a remote control panel for AI coding agents. It lets you monitor, review, and approve agent actions from any device — phone, tablet, or browser — while your source code stays on your laptop or VPS. You get a live feed of streaming tool calls and file edits, an inline diff viewer with syntax highlighting, and a one-tap approval system with five-tier risk classification so you always know what an agent is about to do before it does it. The Switchboard tier adds Linear integration that converts tagged issues into automated pull requests, running 24/7 on your daemon. Per-turn cost tracking shows tokens and USD spend in real time. Agent checkpoints let you roll back unwanted changes. Works with Claude Code, Codex, and OpenCode simultaneously with no wrappers or middleware. Free plan available; Core plan is $10 per month.
