jhansi 0.1.1

Python SDK for jhansi.io - run AI-generated code in isolated sandboxes

Jhansi.io

Build it. Run it. Ship it.

Cloud sandbox for running AI-generated code safely.

---

The problem

Every AI coding tool generates code. None of them answer:

"Where does that code actually run, and what can it touch?"

Paste it into your terminal and hope? That's eval() with access to your .env, your AWS creds, your customer database.

In a startup that's risky. In fintech that's an FCA conversation you do not want to have.

Jhansi.io is the answer.

What it is

A cloud sandbox platform with three layers:

Layer	What it does
Jhansi	SDK, cloud UI, and the API your app talks to. This repo.
Petri	Runs code in isolated Docker containers. Spins up, executes, tears down. Zero state left behind.
TenantVault	Per-tenant secrets injection. AI agents can use secrets but can't read or exfiltrate them.

Repositories

Repo	Status	Description
jhansi-io/jhansi	🟢 Active	SDK — pip install jhansi

Quick start

from jhansi import Sandbox

with Sandbox(language="python") as sb:
    result = sb.exec("print('hello from isolation')")
    print(result.output)

SDK is under active development. Follow this repo for releases.

Petri API

POST   /v1/sandboxes            → Create sandbox, get sb_<id>
POST   /v1/sandboxes/{id}/exec  → Run code, get output
GET    /v1/sandboxes/{id}       → Check status
DELETE /v1/sandboxes/{id}       → Destroy it. Gone.

Multi-language: python · node · go

Roadmap

Full roadmap with target dates: jhansi.io/roadmap

No vaporware. If it's not on the roadmap with a date, we're not building it yet.

Why Jhansi.io?

• Competitors (E2B, Modal, Daytona) are SaaS only — Jhansi.io is open core, self-hostable
• Nobody else combines execution sandbox + secrets vault + compliance audit in one platform
• Built by someone with 18 years in banking who has lived the compliance problem firsthand
• Regulation (FCA, SOC2, EU AI Act) requires audit of AI actions — Jhansi.io provides it
