OpenComputer vs Side Space 2.0: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of OpenComputer and Side Space 2.0 — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
OpenComputer
Digger
Deploy managed AI agents as persistent, always-on cloud VMs with steerable execution and permanent HTTP endpoints.
Key features
- Persistent VMs: Always-on virtual machines with a full filesystem and OS access that survive restarts, so agent state is exactly where you left it.
- Elastic Compute: Resize memory (1-16 GB) and vCPU while a VM is running to match the workload of the agent harness.
- Instant Checkpoints: Snapshot any VM state to fork or roll back in seconds, recovering from bad agent runs without teardown.
- One-Prompt Deploy: Paste a single prompt into Claude Code, Codex, or Cursor to install the CLI, log in, initialize, and deploy an agent end-to-end.
- Permanent Agent URLs: Every deployed agent gets a stable HTTP endpoint reachable from Slack, webhooks, and cron jobs.
- Steerable Mid-Run: Interrupt and redirect long-running agents without killing the session, keeping durable state intact.
- Hibernate & Wake: Pause idle VMs to stop paying for compute and resume them instantly when the agent is needed again.
Best for
- Shipping B2B Agent Platforms: Provide end users of your Lovable/Devin/Bolt-style product with per-user VMs that remember installed dependencies and files across sessions.
- Long-Running Autonomous Tasks: Run overnight research, scraping, or refactor agents that need to persist context across many hours without a sandbox timeout.
- Slack & Cron-Triggered Agents: Wire a permanent agent URL to a Slack app or cron so a team can invoke the same agent state from anywhere.
- Rapid Agent Prototyping from an IDE: Turn a natural-language prompt inside Claude Code or Cursor into a live, invokable agent without provisioning infrastructure.
- Safe Rollbacks for Autonomous Coders: Use checkpoints to fork an agent VM before risky changes and restore instantly if the agent breaks its environment.
Side Space 2.0
Side Space
An AI-powered vertical tabs manager in the browser side panel that helps research, summarize, organize, and chat with your tabs.
