AI Coding Assistants

Codeium

Codeium is the original name of the AI coding assistant now called Devin Desktop. Its maker, then Exafunction, rebranded Codeium to Windsurf on April 4, 2025. Cognition (maker of Devin) announced its acquisition of Windsurf on July 14, 2025, citing $82M ARR, 350+ enterprise customers, and hundreds of thousands of daily active users. On June 2, 2026 Cognition folded the editor into its Devin line, renaming it Devin Desktop and swapping the CLI binary from `surf` to `devin-desktop`. Cascade, Windsurf's built-in coding agent, hits end-of-life July 1, 2026, superseded by Devin Local — a from-scratch Rust rewrite claimed to be ~30% more token-efficient with subagent support. The product is a closed-source, proprietary fork of VS Code, not open source. Current version/status: Renamed Devin Desktop, June 2, 2026 (formerly Windsurf since April 2025, formerly Codeium). License: proprietary SaaS (closed-source VS Code fork). Pricing: Free tier $0/mo (light daily/weekly quota, unlimited Tab autocomplete); Pro $20/mo (raised from $15 in the March 19, 2026 credits-to-quota overhaul); Teams $40/seat/mo; new Max tier $200/mo; Enterprise custom — pricing carried over unchanged into the June 2026 Devin Desktop rebrand. Maintained by Cognition (maker of Devin); acquired Windsurf/Codeium July 14, 2025 from its original maker Exafunction.

🧊Why learn Codeium?

Pick this lineage if you want an agentic VS Code fork with a deep free tier for Tab autocomplete and don't mind chasing a moving target — three names and two pricing overhauls since April 2025. Skip it for long-term API stability; Cursor has kept one name and a steadier roadmap the whole time. Community gripe even Cognition's own FAQ tacitly concedes: existing Windsurf users had zero say in the June 2026 Devin Desktop switch or Cascade's July 2026 sunset — settings carried over, but the product identity did not survive their subscription. Known weakness: Users get zero input on identity or agent-engine churn — three product names and a forced Cascade-to-Devin-Local agent migration inside 15 months, all pushed as automatic over-the-air updates.

.env is a file format and tool used to store environment variables, which are key-value pairs that configure application settings like API keys, database URLs, and other sensitive or environment-specific data. It allows developers to separate configuration from code, making applications more secure and portable across different environments (e.g., development, testing, production). Tools like dotenv in Node.js or python-dotenv in Python parse .env files to load these variables into the application's environment at runtime.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like password protection, custom error pages, and enabling features like mod_rewrite for URL manipulation.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like enabling HTTPS, blocking IP addresses, or setting custom error pages.

.htaccess Redirect

.htaccess redirect is a server-side configuration technique using the .htaccess file on Apache web servers to manage URL redirections, such as redirecting old URLs to new ones, enforcing HTTPS, or handling errors like 404 pages. It operates through directives like Redirect, RedirectMatch, and RewriteRule, allowing developers to control traffic flow without modifying server-wide settings. This method is essential for SEO, user experience, and maintaining link integrity during website migrations or updates.

.NET Interactive

.NET Interactive is an open-source tool that enables interactive programming experiences across multiple languages (C#, F#, PowerShell, SQL, HTML, JavaScript) within notebooks like Jupyter, Visual Studio Code, and Azure Data Studio. It allows developers to create and share executable documents that combine code, visualizations, and narrative text, facilitating data exploration, documentation, and teaching. The tool integrates with the .NET ecosystem, providing rich output capabilities and extensions for data science and machine learning workflows.

.NET Profiling Tools

.NET profiling tools are software utilities used to analyze the performance, memory usage, and behavior of .NET applications during execution. They help developers identify bottlenecks, memory leaks, and inefficiencies by collecting data on CPU usage, garbage collection, thread activity, and method execution times. These tools are essential for optimizing .NET applications to ensure they run efficiently and reliably in production environments.
