Sapilon is an AI-first software system that governs AI to modernize legacy systems and graduate AI prototypes into production-ready, AWS-native software.

Does Sapilon have a subscription?

No. Sapilon uses a prepaid wallet, pay-as-you-go, with no subscription and no seats. You fund a wallet and only pay for what you use.

Do I own the code Sapilon produces?

Yes. Sapilon produces plain Git repositories with open libraries deployed to your own AWS account. There is no vendor lock-in.

Private early access

Modernize your business.

Sapilon turns legacy systems and AI prototypes into production-ready software on your own AWS. Built to last years, not demos.

Join the waitlist to be among the first to modernize your business with Sapilon.

Plain Git Open libraries Native AWS No lock-in

Migrate fast

50–95% of a legacy app rebuilt in the bootstrap phase, ~10× faster than a traditional rewrite.

Built to survive

Lifecycle management, upgrade-aware diffs, and AI-safe ownership zones keep software healthy for years.

You own it

Plain Git, open libraries, native AWS. No lock-in.

How Sapilon modernizes your software

Every project moves through four stages: Design, Build, Rehearsal, and Live. Each one is gated, governed, and reversible. Not a one-shot generation.

01
Design

See the new system before any backend exists.
- A 10-minute guided interview learns your software: size, stack, team, and intent.
- Sapilon proposes an opinionated, AI-safe architecture and a migration roadmap.
- The new frontend is built with mocked data, so you validate the experience first.
02
Build

The governed agent wires it up end-to-end.
- Backend, database, and APIs are generated against best-practice templates.
- The app runs end-to-end on your Build Server, a real dev environment.
- Every AI action is logged, diffable, and reversible inside explicit ownership zones.
03
Rehearsal

A full dress rehearsal before anything goes live.
- Deployed to a pre-production Rehearsal Server in your own AWS.
- Real user journeys are walked through with automated code review and audit.
- Data migration is drilled and security and costs are checked, so go-live holds no surprises.
04
Live

Real users, real data, built to last years.
- The new system takes over on your Live Server; the old one is retired.
- Versioning, upgrade-aware diffs, and monitoring keep it healthy long-term.
- Plain Git, open libraries, and your own AWS, with cost visibility and no lock-in.

From prototype to production

Built an app with an AI builder and hit the wall when it had to become real software? Sapilon imports your prototype and makes it production-grade: proper architecture, tests, governance, and your own cloud. We treat these tools as sources you import from, not just rivals.

AI governance you can trust

Every AI action is logged, diffable, and reversible. Explicit ownership zones make it clear what the AI may touch and what stays under human control.

//!AUTO: AI owns it //!SAFE: AI proposes, human approves //!DEV: humans only

When the AI shouldn't decide alone

Some changes deserve a human: a schema change on a live system, a security judgement, an irreversible data migration. Sapilon's governed gate stops the agent before it acts, a verified expert reviews the decision, and your agent resumes with a verdict and its reasoning.

Reasoning is required for everything except a plain approve. Every rate is published and all-inclusive; Sapilon's share comes out of the price, never on top of it.

Not a vibe-coding toy. A software factory.

Most AI app builders optimize for speed and demos. Sapilon optimizes for software that has to survive: audited, governed, and owned by you. Here is where the difference shows.

The industry problem AI code generation is chaotic: The Sapilon way Opinionated, AI-safe architecture with explicit guardrails and automated review on every generated change.
The industry problem Tools forget your project between sessions: The Sapilon way Persistent project memory: architecture, intent, constraints, and decisions travel with the project.
The industry problem Prototypes die on the way to production: The Sapilon way A lifecycle-aware path that graduates prototypes into governed, tested, deployed software.
The industry problem Legacy systems are stuck: The Sapilon way AI-driven migration: 50–95% of a legacy app rebuilt in the bootstrap phase, ~10× faster than a traditional rewrite.
The industry problem Fear of vendor lock-in: The Sapilon way Plain Git repositories, open libraries, your own AWS account. You can take the code and leave at any time.
