Key Differentiators
| Item | Description |
|---|
GitHub Copilot | Best inline completions — feels like reading your mind. Deep GitHub integration: PR descriptions, code review summaries. Largest user base → most trained. |
Cursor | Standalone AI-first IDE (VS Code fork). Composer for multi-file refactors. Tab for full-line/multi-line edits. Best 'agentic' feel — can modify code across files. |
Codeium | Best free tier (unlimited completions for individuals). Fastest latency of all. Wide IDE support including Eclipse, Vim, and Visual Studio. Command features for terminal. |
Continue | Open-source, BYO-model. Use local models via Ollama for air-gapped environments. Custom slash commands and RAG over codebase. Fully customizable UI and behavior. |
Amazon Q | Deep AWS integration. Infrastructure-as-code generation. Security scanning built in. Best for AWS-heavy teams. Included in AWS accounts. |
Tabnine | On-premise deployment option. Company-specific model fine-tuning. SOC 2 compliance. Best for highly regulated industries. |
JetBrains AI | Native JetBrains integration. Deep understanding of IntelliJ project structure. Best for Java/Kotlin/PHP developers already on JetBrains. |

Workflow Integration
| Item | Description |
|---|
VS Code Users | Copilot or Cursor — Cursor if you want the agent experience, Copilot for pure completions + Chat |
JetBrains Users | JetBrains AI or GitHub Copilot — Copilot has better completions, JetBrains AI has deeper IDE integration |
Privacy-Critical | Continue with local Ollama models — full offline, no data leaving your machine |
AWS Cloud Team | Amazon Q + Copilot — Q for AWS infra code, Copilot for application code |
Budget-Conscious | Codeium (free individual) + Continue + open-source models — zero cost for high quality |
Full AI IDE | Cursor — the most complete AI-native coding experience with Composer, Tab, and inline editing |
Security/Compliance | Tabnine Enterprise — on-premise deployment with company-specific model training |
Pro Tip: Cursor is the best all-round IDE experience (VS Code fork). Copilot has the best inline completions. Continue is free + open-source. Run at least two side-by-side for a week before choosing.
