The Replit alternative that keeps your keys°
Looking for a Replit alternative? Here is the honest comparison for a builder who wants to own their agent — keys, code, and compute.
Where jurniti is different
- A dedicated Firecracker microVM per tenant for the agent you already run (Claude Code, OpenClaw, Codex, Hermes, and the rest of the harness catalog).
- Your model keys live inside the guest; model traffic goes provider-direct — no monthly credit burn to forecast for the model layer.
- Flat monthly pricing for always-on agent ops, not effort-based Agent credits layered on a browser IDE.
- Hardware isolation today as the product, not a container sandbox with a microVM migration still in flight.
| jurniti | Replit | |
|---|---|---|
| Isolation | Per-tenant Firecracker microVM (KVM hardware boundary); 1 vCPU = 1 physical core. | Development sandboxes have run as hardened Linux containers (seccomp-bpf). Replit's own security post states containers are not a perfect isolation boundary and that a microVM replacement is rolling out (not fully complete as of 2026-04-21). Published apps run on GCP (per-customer project claimed). |
| Pricing | Flat $25–$99/mo, no metered surprises. | Starter free with daily Agent credits; Core $25/mo ($20 billed annually) with $25 monthly credits; Pro $100/mo ($95 annually) with $100 monthly credits; Enterprise custom. Verified 2026-07-28 on replit.com/pricing. |
| Model keys | BYOK inside your VM — model traffic never traverses jurniti. | Mixed / platform-mediated: Replit Agent is powered by LLMs behind plan credits and AI integrations — not pure BYOK inside a tenant microVM the way jurniti is structured. |
Where Replit is strong
- A real browser IDE and publish path for full-stack apps — the product most people mean by 'build with an agent in the cloud.'
- Free Starter and Core credit bundles that make Agent exploration cheap without a dedicated agent SKU.
- Multi-agent parallelism and collaboration seats built into Core/Pro (2 parallel agents on Core; 10 on Pro).
- Serious platform security investment, including an announced migration from containers toward microVMs and per-customer GCP projects for deploys.
When to pick one — or both
Pick Replit when you want a browser IDE and Agent that builds and publishes apps, multi-user collaboration, and credit-based Agent usage — not when you need a dedicated hardware-isolated box for an existing agent harness that holds production credentials.
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 Replit — questions
For builders who want a browser IDE and Agent that ships apps, no — Replit owns that product shape. For builders who already run Claude Code (or another harness) and need always-on Firecracker isolation with BYOK, yes: that is the switch jurniti is built for.
As of Replit's April 2026 security post, sandboxes historically used hardened Linux containers, and a microVM replacement was rolling out but not fully complete. jurniti ships per-tenant Firecracker microVMs as the default product boundary today. Re-verify before treating either side as frozen.
Replit Agent usage is tied to plan credits and platform AI integrations. jurniti is pure BYOK inside your guest: you bring the provider key, the key never sits on a jurniti credits balance, and the runtime is the harness you chose — not Replit's Agent product.
