The ecosystem around GitHub Copilot has become a preferred solution for many developers. The tool integrates seamlessly into Visual Studio Code, Visual Studio, and JetBrains IDEs, utilizing OpenAI technology to predict and complete lines of code. The Copilot Chat feature allows dialogue with the AI assistant – you ask questions in natural language, and the system generates functions, explains code, or creates tests.

The tool excels at routine tasks: automatic completion, quick boilerplate generation, and helpful hints during pull request reviews.

Target Audience: Individual developers and teams working in familiar editors who want to benefit from intelligent inline suggestions. Especially valuable for accelerated code creation and small refactorings.

Pricing Structure: Free offering with around 2,000 code completions and 50 chat/agent requests per month. Paid options: Pro for $10/month, Business for $19/month, Enterprise for $39/month. Students and open-source maintainers often get free access.

Google Gemini Code Assist – The Alternative Component

Google has created a tool called Gemini Code Assist based on the Gemini models. It provides context-aware code completions, generates complete functions or files, writes unit tests, and debugs in IDEs like VS Code and JetBrains.

The Gemini CLI extends this with a terminal experience: an open-source agent that analyzes your codebase, manipulates files, executes shell commands, and solves problems directly in the command line. The standard and enterprise editions offer a “Agent Mode” for coordinated multi-file changes and integrations with Google Cloud services.

Target Audience: Developers seeking an AI helper that operates across the entire codebase and can execute terminal commands. Special strengths: full function generation, test automation, and cloud-based workflows.

Pricing Structure: Free for individual users: ~6,000 code requests and 240 chat requests per day. Standard edition: 1,500 requests per user/day; Enterprise: 2,000 requests per day. Pricing tied to Google Cloud subscriptions, often bundled with Workspace or Cloud credits.

The New Generations: IDE-integrated Agents

Cursor AI – The VS Code for the AI Era

Cursor is based on VS Code but weaves AI throughout its architecture. The Agent Mode accepts high-level goals, generates and edits multiple files simultaneously, runs code, and iterates until everything works. Multi-line editing, intelligent rewrites, and precise command execution are standard. You can switch between models from OpenAI, Anthropic, and Gemini, and higher plans offer unlimited completions.

Target Audience: Developers looking for an AI-enhanced editor with a familiar VS Code look. Particularly strong for refactorings across multiple files and realizing complex requirements via the agent mode. Currently one of the most popular “AI Editors.”

Pricing Structure: Free with limited agent requests; Pro $20/month, Pro+ $60/month, Ultra $200/month, Teams $40 per user/month. Enterprise prices are custom.

Windsurf IDE – The Next Level

Windsurf is a native AI IDE that uses a Cascade system for context management across the entire codebase. It offers generative autocomplete, live previews of code changes, automatic linter corrections, and deep code search via the Model Context Protocol. The Supercomplete feature suggests your next action. Natural Language Commands enable function implementation, test execution, and code refactoring.

Target Audience: Developers wanting an AI-first IDE that manages entire projects and handles code generation and execution. The real-time preview and cascade contextualization are especially suited for modern web and mobile development.

Pricing Structure: Free with 25 credits/month; Pro $15/month (500 Credits); Teams $30 per user/month. Enterprise prices are custom.

Google Antigravity – Google’s Experimental Vision

Antigravity is Google’s answer to Cursor and Windsurf – not just an assistant, but an AI-native IDE around Gemini models. An AI agent can plan, think through, write, test, and improve code across your project. The platform is still in early stages but shows Google’s direction in agent-driven development.

Target Audience: Especially suitable for web developers. The system can analyze screenshots of errors and repair code directly. It can click buttons and test websites within the editor.

Pricing Structure: Currently completely free.

Terminal-based Agents: For the Command Line

Claude Code CLI – The Intelligent Terminal Companion

Claude Code is a terminal-based agent that can plan functions, write code, debug errors, search codebases, and execute shell commands. You give commands like “Find the bug in logging.py” or “Write a test case,” and Claude reads files, runs tests, and suggests changes. The skills system allows command chaining and integration of third-party tools. The CLI runs locally or on self-hosted infrastructure – companies retain control over their data.

Target Audience: Terminal-savvy developers wanting an agent for multi-step tasks across a codebase. Especially strong in debugging and refactoring thanks to file reading/modification and test execution capabilities.

Pricing Structure: Available for Claude Pro subscribers (20 USD/month) and Claude Max (ca. 100–200 USD/month). Enterprise implementations require custom pricing and can be self-hosted.

Mistral Vibe CLI – The Fast Open-Source Way

Mistral’s Vibe CLI is an open-source command-line agent powered by Devstral 2. It offers project-based context scanning, intelligent references with (Files) and (Commands), multi-file orchestration, and persistent history. Developers can script it, toggle automatic approvals, and integrate local models via TOML configuration.

Target Audience: Terminal-proficient programmers seeking a fast open-source agent for exploring and editing codebases. Especially useful for navigating large projects and automating repetitive CLI tasks.

Pricing Structure: Free during the Devstral 2 preview. Afterwards, token-based billing: approx. $0.40–2.00 USD per million tokens for Devstral 2, $0.10–0.30 USD per million tokens for Devstral Small.
