Searchers for **AI agent platform** are past the toy phase. They want somewhere to *run* agents: always-on, isolated, with their own keys — not another framework README.

## What the category actually means

An AI agent platform is not:

- A model chat box
- A pure orchestration graph UI
- An ephemeral code-execution sandbox alone
- A browser IDE with an "agent" button

It is the **runtime layer**: where process, filesystem, network, and secrets live while the agent works. If that layer is wrong, frameworks and prompts do not save you.

## The buyer checklist (use it on every vendor)

1. **Isolation** — shared container kernel, or a real guest kernel (Firecracker / KVM)?  
2. **Keys** — BYOK inside the tenant, or a platform credits ledger?  
3. **Uptime shape** — always-on agent, or spin-up-per-call sandbox?  
4. **Harness choice** — one proprietary agent, or install the agent you already picked?  
5. **Economics** — flat monthly for 24/7, or metered seconds that explode when the agent stays awake?  
6. **Ops** — who owns TLS, patches, snapshots, and restore?

Score vendors on those six. Marketing logos are noise.

## Where jurniti sits

[jurniti](/) is a managed **Firecracker microVM** platform for agent harnesses. Each tenant gets a dedicated guest, persistent volume, and BYOK path. You pick Claude Code, OpenClaw, Hermes, Codex, and the rest of the catalog — the platform stays agent-agnostic.

That is different from:

- **Ephemeral sandboxes** (great for one-shot code; painful for always-on bots)  
- **Generic PaaS** (you still invent the agent host)  
- **Cloud IDEs** (human coding sessions, not long-lived agents)  
- **Cheap shared-kernel agent hosts** (density pricing, shared blast radius)

## "Best AI agent platform" is a trap headline

There is no single best. There is a best *for your constraint*:

| Constraint | Prefer |
| --- | --- |
| Burst code execution inside your app | Ephemeral sandbox product |
| Human pair-programming in the cloud | Codespace / CDE |
| Ship a web app + worker | PaaS |
| Always-on agent holding production keys | Dedicated microVM host (jurniti's lane) |

If your brief is "best AI agent platform" because you want parallel coding agents or a messaging bot that never sleeps, evaluate isolation and BYOK first.

## Pricing honesty

jurniti plans start at **$25/mo** (or **$250/year**). Model spend is yours (BYOK). First purchase has a **30-day money-back guarantee**. No free tier — free slots select tire-kickers and burn real compute.

## How to evaluate jurniti in an afternoon

1. Pick the harness you already use on [pricing](/pricing) / the harness landing  
2. Checkout — auto-provision (~minutes, not a sales ticket)  
3. Confirm keys stay in the guest and the agent survives restart  
4. Snapshot or templatize only after you trust the box

## Frequently asked questions

### What is an AI agent platform?

A place that runs agent software for you: compute, isolation, persistence, networking, and lifecycle. Frameworks and model APIs are ingredients. The platform is where the agent actually lives.

### What is the best AI agent platform?

Best depends on the job. Orchestration SaaS, ephemeral sandboxes, cloud IDEs, and managed microVMs solve different problems. If you need always-on agents with production credentials, prioritize hardware isolation and BYOK over chat features.

### Is jurniti an AI agent platform?

Yes — multi-tenant Firecracker microVMs as a service for agent harnesses (Claude Code, OpenClaw, Hermes, and more). Flat monthly pricing, BYOK, 30-day money-back on first purchase.

### Do I need a free trial to evaluate?

jurniti does not offer a free trial or free tier. Every plan has a 30-day money-back guarantee on the first purchase so you evaluate on a real box, not a credits demo.
