HagiCode is a proposal-driven AI coding workbench that turns a request into a reviewable proposal, runs it through agent CLIs such as Claude Code, Codex and GitHub Copilot, and keeps the outcome as team knowledge.
OpenCode is an open-source, MIT-licensed AI coding agent for the terminal, desktop and IDE, with 75+ model providers. HagiCode is a workbench that runs OpenCode as an executor and adds proposals, commit tooling and multi-repo context around it.
OpenCode is an open-source AI coding agent that runs in your terminal, as a desktop app (beta) or in an IDE. It connects to 75+ providers, including your GitHub Copilot or ChatGPT Plus/Pro login, and can run several agents in parallel on one project. HagiCode is a workbench that starts OpenCode as an executor and adds spec proposals, AI commits, multi-repo context and history on top. It does not replace OpenCode and it does not sell models.
OpenCode already covers a lot on its own, including multiple sessions and a desktop app, so many solo developers should stay with it alone. Add HagiCode if you want each change to go through a written proposal, or to manage several repositories and several agents from one place.
Open-source AI coding agent with build and plan agents, LSP support and share links
AI programming workbench that runs agent CLIs, including OpenCode, as executors
Terminal UI, desktop app (beta), IDE extension; macOS, Linux, Windows
Desktop app (Windows, macOS, Linux), Docker Compose container, Microsoft Store edition
MIT-licensed and free; optional OpenCode Zen (pay-as-you-go) and Go ($10/month, as of October 2026) models

75+ providers via Models.dev, local models, Copilot and ChatGPT logins
Hosts no models; uses the providers configured in OpenCode, or OmniRoute if you configure it
Multiple agents can run in parallel on the same project
Several sessions side by side, managed as named Agents
Plan agent is read-only and suggests changes; Tab switches to build
OpenSpec proposals: propose, validate, apply, archive
Left to you or to the agent's shell; sessions can be shared by link
AI-written commit messages with repository locking; Git management in the UI
Permission prompts inside its own interface
Interactive questions are not available for OpenCode in HagiCode
One install command, then /connect a provider and /init
Install OpenCode first, then HagiCode, then pick OpenCode as the Agent CLI
Developers who want an open, provider-flexible agent in terminal, desktop or IDE
Running several OpenCode tasks across repos with specs, review and history in one place
OpenCode connects to 75+ providers through Models.dev and supports local models through OpenAI-compatible endpoints such as Ollama, LM Studio and llama.cpp.
You can sign in with GitHub to use a Copilot account, or with OpenAI to use ChatGPT Plus or Pro, instead of buying separate API credit.
The default build agent has full access for development work. The plan agent is read-only: it denies file edits by default and asks before running shell commands. Press Tab to switch.
A general subagent handles complex searches and multistep tasks and can be invoked with @general.
Use the terminal UI, the desktop app (currently beta) or an IDE extension. OpenCode also runs as a server, and opencode acp starts it as an ACP subprocess for editors.
It loads the right language servers automatically, and /init writes an AGENTS.md so the agent learns your project conventions.
Zen is a curated set of models OpenCode has tested for coding agents, billed pay-per-request. Go is a low-cost subscription: $10 per month, with Go Plus at $40 per month, as of October 2026.
Both are optional. The agent works the same with your own keys, and the official docs state it does not store your code or context data.
HagiCode does not bundle or replace OpenCode. It finds your opencode executable, starts a local server for the project (opencode serve on 127.0.0.1), and sends sessions and prompts to it, so your install, providers and config stay as they are.
The model list comes from the providers you have configured in OpenCode, and HagiCode shows a runtime health state while the server starts.
OpenCode can run agents in parallel inside its own interface. In HagiCode each OpenCode run is a named Agent with visible status next to your other agents, so mixed teams are managed in one place.
OpenCode's plan agent suggests changes; HagiCode's propose, validate, apply, archive flow keeps the plan as a record linked to the diff. Free editions allow 3 concurrent proposals.
HagiCode writes the commit message from your diff and locks the repository while it commits. The embedded Code Server opens files OpenCode changed in a browser editor.
Monospecs lists your repositories in one file so OpenCode starts a proposal knowing the whole change surface. Vault keeps reference projects and notes that complement the AGENTS.md OpenCode already reads.
OpenCode already supports many providers; OmniRoute can add one more routing layer shared across your agents. OpenCode's tool calls use the same format as other agents, and an optional TokenMonitor status-bar item shows today's tokens and cost.
The OpenCode agent is MIT-licensed and free. You pay for models through your own provider keys, an existing Copilot or ChatGPT login, or the optional Zen (pay-as-you-go) and Go ($10/month as of October 2026) plans. See opencode.ai for current pricing.
Run curl -fsSL https://opencode.ai/install | bash, or npm install -g opencode-ai, or brew install anomalyco/tap/opencode. The docs note these methods install OpenCode 1, so check opencode.ai/docs for the current version.
Yes. HagiCode lists OpenCode as an Agent CLI. Install it and connect a provider, then select it in HagiCode; HagiCode starts a local OpenCode server for you.
No. HagiCode is the workbench around OpenCode, adding proposals, commits, multi-repo context and history. It needs OpenCode installed and a provider connected to run.
Yes. OpenCode can sign in with GitHub to use a Copilot account, or with OpenAI to use ChatGPT Plus or Pro. Some Copilot models need a Pro+ subscription.
Pick OpenCode alone if its terminal, desktop or IDE experience covers your work. Add HagiCode if you want proposals, multi-repo context and one workbench for several agents.
