The GitHub Codespaces alternative that keeps your keys°
Looking for a GitHub Codespaces alternative? Here is the honest comparison for a builder who wants to own their agent — keys, code, and compute.
Where jurniti is different
- Flat monthly always-on agent pricing instead of core-hour burn for 24/7 uptime.
- Harness-native install and lifecycle (Claude Code, OpenClaw, …) instead of a generic devcontainer you maintain.
- Product focus on agent isolation and BYOK, not IDE features.
| jurniti | GitHub Codespaces | |
|---|---|---|
| Isolation | Per-tenant Firecracker microVM (KVM hardware boundary); 1 vCPU = 1 physical core. | VM-based compute options hosted by GitHub (configurable core sizes). Dev-environment isolation, not a productized multi-harness agent platform. |
| Pricing | Flat $25–$99/mo, no metered surprises. | Free personal quota (about 120 core-hours/mo on Free — roughly 60 real hours on a 2-core machine) then pay-as-you-go: 2-core about $0.18/hr, up to 32-core about $2.88/hr; storage about $0.07/GB-month. Verified 2026-07-28 from GitHub Codespaces billing docs. |
| Model keys | BYOK inside your VM — model traffic never traverses jurniti. | You configure secrets in the codespace; GitHub does not sell agent BYOK as a product — it sells billed cloud VMs for development. |
Where GitHub Codespaces is strong
- Deep GitHub integration and familiar VS Code / browser workflow.
- Included free core-hours for intermittent personal use.
- Strong fit for human developers who open a repo and code for a few hours.
When to pick one — or both
Pick Codespaces when you want a cloud IDE for human development sessions. Pick jurniti when an agent must stay up and isolated without core-hour math.
Pick jurniti when your agent holds production credentials, runs code an LLM returned, and you want a real per-tenant hardware boundary with your keys inside your VM — at a flat monthly price.

jurniti vs GitHub Codespaces — questions
You can install Claude Code in a codespace. Always-on multi-day agents make core-hour billing painful, and you still own the ops. jurniti is the flat always-on alternative.
