OpenCode makes sense if…
- The terminal is where you already live and work.
- You want a free, open-source agent with no license to buy.
- You like configuring and extending your own tooling.
- You want a client/server setup you can shape yourself.

Limitcode Pro vs OpenCode
These two agree on more than most: both are bring-your-own-key agents that refuse to lock you to one provider. The disagreement is about where the agent should live.
Short answer
OpenCode is a free, open-source coding agent that runs in the terminal with the provider you bring — a strong pick if the TUI is home. Limitcode Pro shares the BYOK philosophy but runs natively inside Sublime Text, with editor-native tools (Send to Agent, permission prompts, snapshot undo/redo, LSP diagnostics) and a one-time license. Terminal-first? OpenCode may be the better fit. Want the agent inside Sublime? Limitcode Pro is designed for that.
01 — At a glance
The short version.
| Aspect | Limitcode Pro | OpenCode |
|---|---|---|
| What it is | A coding agent that works inside Sublime Text | A free, open-source AI coding agent for the terminal |
| Interface | Native side-by-side Sublime Text view | Terminal TUI |
| Sublime Text integration | Native, first-class | None official — hosts like TermMate can dock the CLI |
| Provider model | BYOK: OpenAI, Anthropic, Gemini, DeepSeek, OpenRouter, Copilot, local models | BYOK: many providers, including local models |
| License | One-time purchase, up to 3 devices | Open source, free |
| Editor-native tools | Send to Agent, selection context, snapshot undo/redo, LSP diagnostics | Terminal-driven workflow |
| Setup | Install the package, connect a provider | Install the CLI, run it in a terminal |
02 — The contender
What is OpenCode?
OpenCode is an open-source AI coding agent built for the terminal. It presents a TUI, connects to many model providers with your own keys (including local models), supports LSP integration, MCP servers, and extensibility, and follows a client/server architecture that lets the agent run as a local server with clients attaching to it.
It is free software with an active community, and it is honest about what it is: a terminal-first agent. Editor integration is not the goal — although third-party hosts such as TermMate can dock the OpenCode CLI inside an editor panel.
03 — The challenger
What is Limitcode Pro?
Limitcode Pro is a lightweight coding agent that lives inside Sublime Text (builds 4050+) — no separate AI IDE, and no separate agent daemon required for direct API providers. In a side-by-side chat view it inspects project files, proposes targeted edits for approval, runs approved shell commands, searches the web, loads skills, calls MCP servers, and runs focused subagents under configurable permission rules.
Like OpenCode, it is provider-agnostic: OpenAI, Anthropic, Gemini, DeepSeek, OpenRouter, Copilot, Codex, Antigravity, or local endpoints such as Ollama and LM Studio — switchable per task, with your keys and your accounts. Details on the Providers page.
04 — The core difference
Same philosophy, different home.
Both agents believe you should own the model layer: bring your keys, switch providers, keep local options open. OpenCode expresses that philosophy in the terminal; Limitcode Pro expresses it inside the editor. That single difference changes the daily loop.
In the terminal, context flows through what you type and paste. In Sublime, the agent sits next to your files: the selection you have highlighted, the file you have open, the LSP diagnostics your editor already computed. Limitcode leans into that — Send to Agent passes explicit context with one shortcut, and snapshot undo/redo gives every agent edit a recovery path without leaving the editor.

06 — Pricing
Free and open source vs one-time license.
OpenCode is free, open-source software — you pay your model provider directly for usage. Limitcode Pro is a one-time license valid on up to three devices, with the same rule for model usage: paid directly to the provider you choose, at cost. The open-source Limitcode edition remains free for pair programming, so you can evaluate the workflow before committing to anything.
07 — The honest verdict
Which one should you pick?
Limitcode Pro makes sense if…
- You write code in Sublime Text and want the agent to live there.
- You value editor-native integration: selection context, permission prompts, undo/redo.
- You want a packaged experience with support, not a DIY setup.
- You prefer owning a one-time license over assembling free parts.
08 — FAQ
Questions people actually ask.
Is OpenCode free?
Yes — OpenCode is open source, so the agent itself costs nothing. Like Limitcode, it is bring-your-own-key: you pay your model provider directly for what you use. Limitcode Pro adds a one-time license for the packaged, editor-native experience; the open-source Limitcode edition remains free for pair programming.
Does OpenCode work with Sublime Text?
Not natively. OpenCode is a terminal TUI, and there is no official Sublime Text plugin. Hosts such as TermMate can dock the OpenCode CLI inside an editor panel — but the agent doing the work is still the CLI, with its own runtime and approvals. Limitcode Pro is a native Sublime package, not a hosted CLI.
Both are BYOK — so what is actually different?
Where the agent lives and how much it integrates with the editor. OpenCode gives you a strong terminal UI and gets out of the way of how you configure it. Limitcode Pro gives you the agent inside Sublime Text: send the selection or active file with one shortcut, get editor prompts for permissions, snapshot undo/redo for agent edits, and LSP diagnostics fed back into the loop.
Can I use the same providers in both?
Largely yes. Both connect to the major API providers and to local OpenAI-compatible endpoints such as Ollama and LM Studio. Availability of specific models depends on each tool's provider adapters — check the Providers page for Limitcode's current list.
Which should I pick?
If you enjoy living in the terminal and want a free, open-source TUI agent, OpenCode is a solid choice. If you want the agent to live inside Sublime Text — next to your files, with editor-native tools and a one-time license — Limitcode Pro is built for that.
