Augment Code alternatives: 8 open-source picks
These 8 Augment Code alternatives replace it for $0, led by OpenCode, Cline and Goose. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
A fast local coding agent with no loyalty to any model vendor.
licenseMIT
runson your machine
installInstall with the shell script, Homebrew, npm or Bun; a desktop app is also available
enginesA broad provider catalog covering hosted, OpenAI-compatible and local model endpoints, including optional OpenCode Zen or Go services
dataProject files remain local; configuration, sessions and snapshot metadata are local, and a session is uploaded only when the user explicitly shares it, while prompts go to the chosen provider
the catch vs Augment CodeIt lacks an equivalent to Augment's persistent managed index for navigating very large or cross-repository codebases.
setupConfigure a provider credential or local model unless using a separately billed OpenCode model service
facts verified 2026-08-10
A code agent in your editor; the model bill is still yours.
licenseApache-2.0
runson your machine
installInstall from the VS Code or JetBrains marketplace, or install the Cline CLI
enginesCline account models or bring-your-own-key providers including Anthropic, OpenAI, Gemini, Azure, Bedrock, Vertex and OpenRouter, plus local Ollama and LM Studio models
dataRepository edits stay in the local workspace; extension/session settings are local, while selected workspace context and prompts go to the chosen model provider
the catch vs Augment CodeIts context is gathered around the active workspace, not Augment's persistent managed large-codebase index and enterprise context layer.
setupSign in to Cline or configure a provider API key or local model
facts verified 2026-08-10
A desktop agent that edits and runs code without pretending the model is free.
licenseApache-2.0
runson your machine
installDownload the desktop app or use Homebrew/packages; the CLI also has an install script
enginesMore than 15 providers including Anthropic, OpenAI, Google, Ollama, OpenRouter, Azure, Bedrock and ACP or subscription-backed agents; tools connect through MCP
dataSessions live in a local SQLite database under the user's Goose data directory and can be exported as JSON or Markdown; configuration is local and prompts go to the selected provider
the catch vs Augment CodeIt can edit and run code, but it lacks Augment's managed large-repository indexing and deeply IDE-native context retrieval.
setupConfigure a model provider key, supported subscription, or local model before useful work begins
facts verified 2026-08-10
It edits the repo from a terminal and commits its own mess.
licenseApache-2.0
runson your machine
installPython installer (pip install aider-install, then aider-install) or pipx
enginesLiteLLM-backed providers including OpenAI, Anthropic, Gemini, OpenRouter, Azure, Bedrock, Groq and OpenAI-compatible endpoints, plus Ollama and other local models
dataEdits and Git commits stay in the local repository; chat/input history is stored in local dotfiles, while selected code and prompts are sent to the configured model backend
the catch vs Augment CodeIts repository map is useful, but it does not match Augment's persistent managed indexing and context across very large, multi-repository codebases.
setupA terminal, a Git repository, and either a provider API key or a working local model server
facts verified 2026-08-10
Repository-aware agents across VS Code, JetBrains and the terminal; inference still has a meter somewhere.
