Augment Code

Augment Code is an AI coding platform built specifically for large, complex codebases where naive retrieval and context stuffing break down. Its differentiator is the Context Engine: a proprietary indexing and retrieval system that keeps a fresh, high-fidelity map of an entire monorepo (millions of lines, dozens of services, deep dependency graphs) and surfaces exactly the code the model needs for each request — without dumping the whole repo into context. Augment ships plugins for VS Code, JetBrains, and Vim/Neovim; an Auggie CLI agent for scripted or terminal-native workflows; and integrations with Slack and GitHub for PR review and issue triage. Its Agent mode plans and executes multi-file changes with tool use, and Instructions/Guidelines let platform teams codify org standards. Augment is popular at companies with truly large codebases — Lemonade, Datadog, and various financial services shops have publicly discussed their use — and offers enterprise deployment options including private VPC. Pricing has a Developer tier ($30/mo), Pro ($60/mo), Teams tier, and Enterprise with SSO, SOC 2, audit logs, and custom retention. For engineering leaders whose codebase has already outgrown vanilla Copilot's context window, Augment is one of the most credible enterprise-focused alternatives.
