Assistants and coding agents for developers and teams.

Replit AI

coding · coding

$0/mo · freemium · Free tier

Replit AI is an AI-powered coding assistant embedded directly into Replit's browser-based cloud IDE, eliminating the need for any local setup, dependency management, or infrastructure configuration. It can generate entire projects from a natural language description, explain existing code, and debug errors inline without leaving the browser tab. One-click deployments mean a working prototype can be live within minutes of being written, making it an unusually fast path from idea to deployed application. It is particularly popular with students, educators, and non-technical builders who need to write and run code without the overhead of a traditional development environment.

Best for: Students and beginners who want to learn coding without dealing with local environment setup

Windsurf

coding · coding

$0/mo · freemium · Free tier

Windsurf is an agentic AI IDE built by Codeium, designed around the idea that AI should be able to plan and execute complex coding tasks autonomously rather than just responding to individual prompts. Its Cascade agent can take a high-level instruction, break it into steps, write code, run the terminal, fix errors, and iterate until the task is complete — all with minimal human intervention. The Flow paradigm keeps the AI continuously aware of what the developer is doing, so context is never stale when the agent acts. Fast inline completions are handled by Codeium's own purpose-built model, giving a responsive day-to-day editing experience alongside the more powerful agentic capabilities.

Best for: Developers who want an agentic AI that can execute complex, multi-step tasks from a single high-level instruction

GitHub Copilot

coding · coding

$10/mo · freemium · Free tier

GitHub Copilot is Microsoft and OpenAI's AI coding assistant, offering inline code completions across every major IDE including VS Code, JetBrains, Neovim, and Visual Studio. Copilot Chat adds an in-editor conversational interface for explaining code, debugging, and answering questions about the codebase. Copilot Workspace extends the experience further by taking a GitHub issue and orchestrating the changes needed to resolve it, producing a ready-to-review pull request. With over 1.8 million active developers, it is the most widely adopted AI coding assistant available.

Best for: Teams already on GitHub who want AI assistance woven into their existing PR and issue workflows

JetBrains AI Assistant

coding · coding

$10/mo · freemium · Free tier

JetBrains AI Assistant is the official AI integration for the full suite of JetBrains IDEs, including IntelliJ IDEA, PyCharm, WebStorm, GoLand, and Rider. It provides in-editor chat, inline completions, and context-aware suggestions that are informed by JetBrains' own deep language analysis engine — giving it a level of project awareness that external plugins cannot replicate. Practical workflow features like AI-generated commit messages and automatic unit test generation integrate directly into existing JetBrains UI patterns, requiring no change to how developers already work. A single subscription activates AI Assistant across all JetBrains products, making it a natural fit for polyglot teams standardised on the JetBrains ecosystem.

Best for: Java, Kotlin, Python, and Go developers who live in JetBrains IDEs and want AI assistance without switching editors

Amazon Q Developer

coding · coding

$19/mo · freemium · Free tier

Amazon Q Developer is AWS's AI coding assistant, offering inline completions and a conversational interface in VS Code and JetBrains with deep native understanding of AWS services, SDKs, and infrastructure patterns. Beyond completions, it includes a code transformation feature that can automatically upgrade Java applications across major versions — a task that typically requires weeks of manual effort. Built-in security scanning detects vulnerabilities and exposed credentials in real time, surfacing issues before code is committed. It also extends into the AWS console and CLI, helping engineers understand service configurations, troubleshoot CloudWatch errors, and navigate AWS documentation without leaving their current context.

Best for: AWS-focused engineering teams who want AI suggestions that understand IAM, CDK, Lambda, and other AWS services natively

Gemini Code Assist

coding · coding

$19/mo · freemium · Free tier

Gemini Code Assist is Google's AI coding assistant, powered by Gemini models and available as an extension for VS Code, JetBrains IDEs, and Google Cloud Shell. Its headline differentiator is a context window of up to one million tokens, making it possible to load and reason over very large codebases in a single query — a capability that competing tools cannot match at this scale. It has deep first-party integration with Google Cloud Platform, providing accurate and up-to-date suggestions for services like Cloud Run, BigQuery, Vertex AI, and Cloud Functions. Enterprise deployments support VPC Service Controls and customer-managed encryption keys for teams with strict data governance requirements.

Best for: Teams building on Google Cloud who want an AI coding assistant that understands GCP services natively

Cursor

coding · coding

$20/mo · freemium · Free tier

Cursor is an AI-first code editor built as a fork of VS Code, designed from the ground up to make AI a first-class part of the coding workflow rather than a bolt-on. Its Tab completion goes well beyond single-line suggestions, predicting and inserting multi-line edits that match the developer's intent across the current context. Composer mode lets developers describe a large change in natural language and have Cursor coordinate edits across multiple files simultaneously, making it well-suited for feature development and large refactors. Cursor supports any major LLM — including GPT-4, Claude, and Gemini — and has grown faster than any other AI IDE.

Best for: Individual developers who want the most capable AI-assisted editing experience in a familiar VS Code environment

T

Tabnine

coding · coding

$39/mo · paid-only

Tabnine is an AI code completion assistant built around a privacy-first architecture, making it the go-to choice for enterprises with strict data security and IP requirements. Unlike cloud-only competitors, Tabnine can run its models entirely on-device or on a private cloud deployment, ensuring that source code never leaves the corporate environment. Its training data is limited to permissively-licensed open-source code, which removes the licence contamination risk that concerns legal teams at large organisations. Tabnine holds SOC 2 Type II certification and supports enterprise access controls, audit logging, and SSO.

Best for: Enterprises in regulated industries — finance, healthcare, defence — where code cannot leave the corporate perimeter

S

Sourcegraph Cody

coding · coding

$59/mo · paid-only

Sourcegraph Cody is a codebase-aware AI coding assistant that uses Sourcegraph's code intelligence graph to understand entire large repositories, not just the files currently open in the editor. This makes it possible to ask questions like 'how does authentication work across this service?' and receive an accurate, cross-file answer grounded in the actual codebase rather than general training data. Cody supports multiple LLMs — including Claude, GPT-4, and Gemini — and can be switched per query depending on the task or data residency requirements. It is available as VS Code and JetBrains extensions, and can be self-hosted for enterprises that require source code to remain on their own infrastructure.

Best for: Large engineering organisations with sprawling monorepos who need AI that can answer questions across the entire codebase

D

Devin

coding · coding

$500/mo · paid-only

Devin, built by Cognition, is the first commercially available fully autonomous AI software engineer, capable of completing entire engineering tasks end-to-end without step-by-step human guidance. Given a ticket or task description, Devin reads the requirements, writes code, executes tests, fixes failures it encounters, and opens a pull request for review — operating inside a sandboxed environment with its own shell, browser, and editor. It integrates with GitHub and Linear so it can be assigned issues directly through existing engineering workflows. Unlike AI coding assistants that require a developer at the keyboard, Devin is designed to operate as a parallel team member working independently on well-scoped tasks.

Best for: Engineering teams that want to delegate well-defined, self-contained implementation tickets to an AI agent
