GitHub Copilot vs Greptile
Side-by-side comparison of features, pricing, ratings, and alternatives.
GitHub Copilot is an AI coding assistant that provides inline code completions, whole-function suggestions, and a chat interface directly inside popular editors like VS Code, Visual Studio, and JetBrains IDEs. It is trained to understand context from open files and comments to suggest relevant code as developers type. Copilot Chat lets developers ask questions about their codebase, request explanations of unfamiliar code, or generate unit tests conversationally, while Copilot Workspace extends this into planning and implementing multi-file changes from a single natural language task description. Business and Enterprise tiers add organization-wide policy controls, code referencing filters, and integration with GitHub Enterprise for teams that need governance over AI-assisted development.
Greptile is an AI-powered code review tool that builds a graph index of an entire codebase, mapping files, functions and dependencies, then deploys multiple review agents in parallel to check pull requests for bugs, security issues and style violations. It continuously learns from a team's own PR comments to apply house coding standards automatically. Greptile also includes TREX, a testing agent that autonomously writes and runs tests for a given PR, and supports custom rules written in plain English. It integrates with GitHub and GitLab, plugs into coding agents like Claude Code, Cursor, Codex and Devin, and offers a self-hosted, SOC 2-compliant option for enterprise security requirements.
Free tier for limited use; Individual plan $10/month, Business $19/user/month.
- Deep integration across major editors
- High-quality, context-aware suggestions
- Copilot Chat useful for explanations and debugging
- Business tier adds strong governance controls
- Free Starter tier covers a solo developer with unlimited repositories
- Whole-codebase graph indexing gives reviews more context than diff-only tools
- TREX can generate and run tests automatically instead of just flagging missing coverage
- Plain-English custom rules are easier to set up than a rules DSL
- Suggestions occasionally need significant correction
- Free tier is quite limited
- Requires careful review to avoid subtle bugs
- Credit-based Pro pricing means heavy TREX usage (3 credits per review) can burn through the allotment fast
- Full language accuracy is strongest on a defined set of languages, with reduced accuracy on others
- Self-hosted deployment likely requires an Enterprise conversation not detailed publicly

GitHub Copilot Reviews
4.0 (4)Solid choice
We've been using GitHub Copilot for a few months now and it's genuinely made a difference for our team. Business tier adds strong governance controls. One minor gripe: free tier is quite limited, but it hasn't been a dealbreaker. Would recommend to anyone considering it.

The Verdict
AI-generated from listing dataGreptile offers AI code‑review with whole‑codebase context and auto‑test generation, while GitHub Copilot focuses on inline code completion and chat assistance.
Key differences
- •Greptile indexes the entire repository and runs swarm review agents; Copilot only sees the current file/region.
- •Greptile can auto‑write and execute tests (TREX); Copilot offers test generation but not autonomous execution.
- •Greptile lets non‑technical users create review rules in plain English; Copilot has no custom rule engine.
- •Copilot integrates deeply with many IDEs (VS Code, JetBrains, Visual Studio, Neovim); Greptile’s integrations are limited to Git platforms and a few coding agents.
- •Pricing model: Greptile’s free tier is unlimited repos for a solo dev, but Pro uses credit‑based usage; Copilot charges per user after a limited free tier.
