5 alternatives to GitHub Copilot
Compare free and open-source solutions before building your own. Check each option’s license, setup, and limitations.
A fast local coding agent with no loyalty to any model vendor.
LicenseMIT
PlatformsOn your machine
InstallationInstall with the shell script, Homebrew, npm or Bun; a desktop app is also available
ModelsA 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
Limitations compared to GitHub CopilotIt is agent-first and lacks Copilot's equally seamless inline completions and integration across GitHub and existing editors.
SetupConfigure a provider credential or local model unless using a separately billed OpenCode model service

A fast open editor with completions, chat and agents built in; model usage is separate.
LicenseGPL-3.0+
PlatformsOn your machine or in the cloud
InstallationInstall the native app from Zed or an operating-system package manager on macOS, Linux or Windows
ModelsZed-hosted models, bring-your-own-key providers, local Ollama, LM Studio or llama.cpp models, and ACP-compatible coding agents
DataProject files stay on the local or SSH-accessed machine and app state is local; hosted or BYOK prompts go to the selected provider, while collaboration state uses Zed's cloud
Limitations compared to GitHub CopilotIt requires switching editors, while model usage is separate and Copilot works across more existing editors and GitHub surfaces.
SetupNone for the editor itself; AI requires a Zed account, provider key, local model, or external agent

A code agent in your editor; the model bill is still yours.
LicenseApache-2.0
PlatformsOn your machine
InstallationInstall from the VS Code or JetBrains marketplace, or install the Cline CLI
ModelsCline 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
Limitations compared to GitHub CopilotIt is agent-first and separately model-billed, with weaker low-latency inline completions and GitHub-native integration than Copilot.
SetupSign in to Cline or configure a provider API key or local model

Copilot-shaped completions and chat, paid for with your own GPU instead of a seat.
LicenseApache-2.0
PlatformsOn your server
InstallationRun the server from Docker or a standalone binary, then connect an editor extension
ModelsLocal llama.cpp-backed completion, chat and embedding models or separately configured remote HTTP model endpoints
DataModels, configuration, logs, indexed source and Tabby's database live under TABBY_ROOT, which defaults to the user's .tabby directory
Limitations compared to GitHub CopilotCompletion quality and latency depend on the chosen model and hardware, and the GitHub and editor experience is less turnkey than Copilot.
SetupDownload and size suitable models, provide enough GPU or RAM, start the server, and configure each editor client
Facts verified 2026-08-10
One open agent across VS Code, JetBrains and the terminal; inference still has a meter somewhere.

They pay because low-latency completion and repo-aware coding are available in their editor without setup. If those points do not matter to you, the options above could save $120 per year.
Is there a free alternative to GitHub Copilot?
Yes: OpenCode, Zed, Cline. This page lists 5 free or open-source options. Check the limitations of each.
Should I build my own GitHub Copilot?
Our verdict: With trade-offs. You can use open-source editor agents and local/API models, but Copilot's value is editor integration, model routing, GitHub context, completions, and managed usage. The complete prompt is on the GitHub Copilot page on Vibe Radar.
