GitHub’s assistant for VS Code, JetBrains, and the GitHub site, offering completions, chat, code review, and a coding agent. Agent mode plans and executes multi-step tasks across files and the terminal, and you can pick among models. Deeply integrated with pull requests and the GitHub workflow.
Pricing Free tier (limited); Pro $10/mo, Pro+ $39/mo, Business $19/user/mo, Enterprise $39/user/mo
Best for Teams living in GitHub who want a mature, broadly-integrated assistant
An Apache-2.0 VS Code extension (formerly Claude Dev) that reads and edits files, runs terminal commands with approval, and works through tasks with human checkpoints. It is bring-your-own-key — connect Anthropic, OpenAI, OpenRouter, Bedrock, Vertex, or local models and pay providers directly. Also ships as an SDK and CLI.
Pricing Free & open source; bring your own API key and pay the model provider directly
Best for Devs who want a transparent, open agent inside VS Code with full key control
A fast-moving open-source fork of Cline built around custom modes — Code, Architect, Ask, Debug, and personas you define with scoped tool permissions. "Boomerang" sub-tasks return results to the parent thread and a memory bank persists project context. Diff-based edits keep token costs down.
Pricing Free & open source; bring your own API key and pay the model provider directly
Best for Power users who want granular modes, custom personas, and rapid releases
An MIT-licensed assistant for VS Code, JetBrains, and Neovim with chat, autocomplete, and an agent mode that plans and executes multi-step tasks. In 2026 it leaned into source-controlled AI rules and continuous AI — checks you can enforce in CI to keep a "software factory" consistent. Fully bring-your-own-model.
Pricing Free & open source; bring your own model (cloud, local, or 100+ providers)
Best for Privacy-minded or JetBrains devs who want open, customizable, CI-enforceable AI
An enterprise-grade assistant built for compliance: zero code retention, no training on your code, and SaaS, VPC, on-prem, or fully air-gapped deployment. It offers completions, SDLC chat, and an agentic platform across major IDEs, with access to multiple LLMs. SOC 2, GDPR, and ISO 27001 certified.
Pricing Code Assistant $39/user/mo, Agentic Platform $59/user/mo, Enterprise custom (14-day trial)
Best for Regulated teams (finance, healthcare, defense) that need code to stay in-house
An agent for VS Code and JetBrains whose Context Engine indexes hundreds of thousands of files across many repos, so it understands how a change connects across a large system. It runs MCP and native tools, does not train on your data, and is SOC 2 Type II. The standout pick when scale is the problem.
Pricing Indie $20/mo, Standard $60/mo, Max $200/mo (credit-based, with auto top-up)
Best for Engineers in large monorepos or microservice fleets who need deep context
