BelioBot — AI SaaS Platform
A multi-model AI SaaS, live and billing paying subscribers from launch day.
BelioBot — AI SaaS Platform
Overview
BelioBot is a production AI SaaS platform that generates images, video, music, code, and text through a single interface. It launched live with Stripe subscription billing and has served paying subscribers from day one, with five AI modalities unified behind one abstraction layer.
The Challenge
What needed to change
Shipping a multi-model AI product is not a prototype problem — it is a production engineering problem. Each AI provider has a different API, different failure modes, and different costs, and stitching them together naively leads to brittle code and runaway API bills. On top of that, a real SaaS needs subscription billing, plan enforcement, and accounts that work correctly from the first paying customer. Getting any of that wrong means lost revenue, uncontrolled spend, or a product that cannot scale past launch.
Our Approach
How we engineered it
We designed BelioBot to be production-grade from day one, starting with a unified API abstraction over multiple AI providers so the product is not coupled to any single vendor. We integrated Stripe subscription billing with plan enforcement and usage metering, so free and pro tiers are enforced in code rather than by trust. We added per-request cost controls to prevent runaway API spend — essential when every request costs real money to a third party. Full auth, account management, and an admin dashboard for usage and billing round it out, all deployed on production infrastructure built to handle real load.
What We Built
The systems behind the result
Unified multi-provider AI layer
A single abstraction over OpenAI, Replicate, and other providers exposes five modalities — image, video, music, code, and text — through one consistent interface.
Stripe subscription billing
Free and pro plans are managed entirely through Stripe with plan enforcement and usage metering, so billing runs without manual intervention.
Per-request cost controls
Cost guards on every request prevent runaway third-party API spend — a critical safeguard when each generation has a real provider cost.
Auth and account management
Full authentication and account management support a real subscriber base correctly from the first paying user.
Admin usage and billing dashboard
An admin dashboard surfaces usage and billing so the platform can be operated and monitored without spelunking through logs.
The Impact

manual billing management — Stripe handles everything automatically
Tech & Why
The stack, and the reasoning
Next.js and TypeScript give a type-safe, full-stack foundation that scales from the UI to the API routes coordinating providers. Routing every model through one abstraction over OpenAI, Replicate, and others avoids vendor lock-in and keeps cost controls centralized, while Stripe removes an entire class of billing bugs. Deploying on Vercel with PostgreSQL kept the platform production-ready and scalable from launch.
