# OpenCode Hosting on a Real microVM > Run SST's OpenCode — the open-source, provider-agnostic terminal coding agent — on its own always-on Firecracker microVM. Any model, BYOK with no markup, a persistent home, real isolation. 124ms boot, 30-day money-back. - Published: 2026-06-07 · Updated: 2026-06-07 · jurniti - Canonical: https://www.jurniti.com/blog/opencode-hosting OpenCode crossed 100,000 GitHub stars and topped Hacker News because it does one thing the subscription CLIs won't: it talks to *any* model and never takes a cut of your tokens. Same Claude or GPT, no markup. The catch is the same as every terminal agent — it runs `bash` on whatever machine you put it on. Here's how to get the best of it without the risk: run [OpenCode](/opencode) on its own always-on Firecracker microVM. Any provider you want, a persistent workspace, hardware isolation from your laptop — booting in about 124ms. ## What OpenCode is OpenCode is an open-source (MIT) coding agent for the terminal, from the team behind SST. It opens a rich TUI, connects to the provider you choose, and writes, debugs, refactors, and documents code from the command line. It's **provider-agnostic by design** — 75+ providers, including fully local models via Ollama — with LSP-powered, type-aware edits and parallel multi-session support. The pitch is control: you own the model choice, you own the keys, and the core agent is free. The thing it needs is a place to run with a shell and your files — always on, holding your project. ## Why a real microVM for OpenCode A coding agent runs `bash`. It installs packages, edits files, and executes whatever the model decides — code no human reviewed. On your laptop that's your whole machine on the line. A shared container isn't the answer either: it shares the host kernel, with 200-plus known weaknesses in the stack. **jurniti gives OpenCode its own Firecracker microVM** — its own kernel, a KVM hardware boundary, one tenant per box. The same isolation serverless platforms use. Give the agent root inside its own VM and a bad command — or a poisoned dependency, or a prompt-injection attack — stays contained to that box. Reprovision and you're clean in seconds. **BYOK is where OpenCode shines, and jurniti makes it architectural.** If you already pay for Anthropic or OpenAI API credits, OpenCode with your own key is the cheapest way to a Claude- or GPT-powered terminal agent — no subscription, no markup. Run `opencode auth login`, point it at any provider, and the key lives only in your VM. Traffic leaves straight for the provider. jurniti is never in the path and never marks up a token. OpenCode runs comfortably on **Starter (1 vCPU / 2 GiB)**. And it's reversible: a **30-day money-back guarantee**, workspace kept 7 days after cancellation. ## Run OpenCode in 3 steps By hand this is a VPS, the install script, provider config, a systemd unit, tmux so sessions survive a disconnect, and patching for as long as you run it. jurniti runs the box; you keep the agent. ### 1. Pick a plan and pay [Starter](/pricing) is enough for OpenCode. Check out, and the provision chain runs automatically the moment payment confirms. ### 2. Your microVM boots with OpenCode ready A fresh Ubuntu microVM boots with OpenCode pre-installed and on your PATH. You get an in-browser terminal — nothing to SSH into. Configure a provider and go: ```bash opencode auth login # pick any provider, paste your key opencode ``` ### 3. Put it to work Drop into a project, hand OpenCode a task, and walk away. Your config and custom agents live on the persistent home, so they survive every restart. ## What people run OpenCode for - **Model freedom.** Swap between Claude, GPT, Gemini, Groq, or a local Ollama model without changing tools. - **Cheapest Claude-in-the-terminal.** BYOK against API credits you already have, no subscription on top. - **Long, thorough runs.** OpenCode trades a little speed for depth and real LSP diagnostics — let it grind on a box that's always on. - **A pinned environment.** Your config, your custom agents, your provider keys — set up once, always there. Snapshot a dialed-in workspace into a [template](/templates) and fork it for the next project — your setup, never your credentials. ## jurniti vs a laptop vs a DIY VPS | | jurniti | Your laptop | DIY VPS | |---|---|---|---| | Always on | Yes | No — it sleeps | Yes | | Isolation for `bash` | Firecracker microVM (KVM) | Your whole machine | Shared kernel | | Provider keys | Yours, never leave the VM | Yours | Yours | | Token markup | None (true BYOK) | n/a | None | | Setup | Automatic · 124ms boot | Local install | Manual | | Refund | 30-day money-back | n/a | None | ## Pricing Starter is **$25/mo** ($250/year, two months free) and comfortably runs OpenCode. Pro is **$49/mo** and Max **$99/mo** for heavier workspaces or a custom TLS subdomain. Every plan includes the 30-day money-back guarantee, and your model spend is separate and never marked up.

OpenCode is an open-source (MIT), provider-agnostic coding agent for the terminal, built by the team behind SST. It opens a TUI, connects to the model provider of your choice, and writes, debugs, refactors, and documents code from the command line. It speaks to 75+ providers — Anthropic, OpenAI, Gemini, Bedrock, Groq, OpenRouter, and any local model via Ollama — so you're never locked to one vendor. ### Can I run OpenCode on a server? Yes. OpenCode is terminal-first, so an always-on box lets it keep working on long tasks and hold a persistent workspace. jurniti runs OpenCode on a dedicated Firecracker microVM with an in-browser terminal and a persistent home — hand it a task, close your laptop, come back to a finished diff. ### Do I need my own API key? Yes, and that's the point. OpenCode with BYOK is the cheapest path to a Claude- or GPT-powered terminal agent — same model, no subscription markup. Run `opencode auth login` to configure any provider. Your keys stay in your VM, traffic goes straight to the provider, and jurniti never marks up a token. ### How much does it cost to host OpenCode? Plans start at $25/mo ($250/year — two months free), and every plan has a 30-day money-back guarantee. OpenCode runs comfortably on Starter (1 vCPU / 2 GiB). Your model spend is separate and never marked up, because you bring your own key. ### Will my config and custom agents survive a restart? Yes. Your home directory is on a persistent volume, so your OpenCode config and custom agents survive restarts and reprovisions. You can also snapshot the whole setup into a forkable template — credentials are scrubbed on publish. ### Is this an official OpenCode product? No. jurniti is independent managed hosting for the open-source OpenCode agent. We install the upstream package at first boot — no fork — so you run the real OpenCode and pick your own provider and version.
