The Modal alternative that keeps your keys°
Looking for a Modal alternative? Here is the honest comparison for a builder who wants to own their agent — keys, code, and compute.
Where jurniti is different
- Always-on agent with flat monthly price instead of per-second serverless for a process that never idles.
- Named harness installs and dashboard for non-ML-platform users.
- Firecracker per-tenant default vs gVisor sandbox jobs.
| jurniti | Modal | |
|---|---|---|
| Isolation | Per-tenant Firecracker microVM (KVM hardware boundary); 1 vCPU = 1 physical core. | gVisor-based sandboxing for untrusted code (stronger than plain containers; not the same as a dedicated Firecracker guest kernel per jurniti tenant). |
| Pricing | Flat $25–$99/mo, no metered surprises. | Usage-based serverless: CPU/GPU and sandboxes billed per second (or finer), with free/starter credits common on the public product. No flat always-on agent SKU. Re-verify current unit rates on modal.com/pricing before any sales quote. Verified posture 2026-07-28. |
| Model keys | BYOK inside your VM — model traffic never traverses jurniti. | Your code brings keys into jobs/sandboxes. Modal is compute infrastructure, not an LLM credits middleman — still not a managed agent harness SKU. |
Where Modal is strong
- Excellent for bursty GPU/CPU jobs and ML pipelines.
- Per-second billing matches short-lived sandboxes and batch work.
- Python-native developer experience for data/ML teams.
When to pick one — or both
Pick Modal for serverless AI jobs and ephemeral sandboxes. Pick jurniti for a dedicated always-on agent microVM.
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 Modal — questions
Modal is serverless AI compute. jurniti is managed always-on agent hosting. If your agent must stay up 24/7 with a harness UI, jurniti matches; if you run short jobs, Modal matches.
