Replit AI

coding · coding

Free · 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

Devin Desktop (formerly Windsurf)

coding · coding

Free · freemium · Free tier

Devin Desktop is the successor to Windsurf, announced by Cognition on June 2, 2026. It combines an IDE with a manager for local and cloud coding agents. Spaces group sessions and shared context, while ACP support allows compatible agents to use the same interface. Devin Local succeeds the former Cascade agent.

Best for: Developers working with several coding agents

GitHub Copilot

coding · coding

$10/mo · freemium · Free tier

GitHub Copilot provides code completion, chat, and agent workflows across supported editors and GitHub. Its coding agent can work on repository tasks and create pull requests for review. The former Copilot Workspace technical preview was sunset on May 30, 2025. Availability and usage allowances vary by plan.

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 · free · 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 a code editor with AI completion and agent workflows. It can inspect repository context, coordinate edits across files, and run tools to help implement and debug changes. Developers can choose among supported models, subject to plan and usage limits.

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

Devin

coding · coding

$20/mo · freemium · Free tier

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

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

Sourcegraph Cody

coding · coding

Check provider pricing · paid-only

Cody is Sourcegraph's code assistant for enterprise deployments, with repository context and support for organization-managed models. Cody Free, Pro, and Enterprise Starter were discontinued on July 23, 2025. Enterprise customers should confirm availability and pricing with Sourcegraph; the former $59 per-seat figure is not a current self-serve quote.

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