architecture · production stack

Built on a real production stack.

Every uStack application ships through ustack Autobuild™ — our industrialized production pipeline — onto the same foundation a senior engineering team would choose: Next.js, Postgres, Prisma, GitHub, Vercel. Anyone you hire already knows the stack. Your engineers continue building from day one. No proprietary runtime, no rebuilds when you outgrow the demo.

// the production methodology

The ustack Autobuild™ pipeline.

Industrialized custom software. Every uStack application — from the $99 trial through a multi-week enterprise build — runs through the same four-step pipeline.

// step 01

Structured spec

7-stage guided intake turns your paragraph into a machine-readable spec — entities, actors, workflows, requirements, acceptance criteria.

// step 02

REQ-by-REQ build

The Autobuild™ build agent writes code one requirement at a time. Audit ledger records every action. Cost guards prevent runaway runs.

// step 03

Automated quality checks

Every requirement gets an end-to-end test. The results ride along in the build record, and we never ship a build we judge to be broken. Failed builds are free.

// step 04

Deployed app

Live URL inside 24 hours. GitHub repo + database export transferable on day one. Same pipeline ships every change.

Authentication + sessions

Magic-link sign-in · org-scoped roles · rate-limited · audit-logged

Postgres schema + migrations

Versioned migrations · seed data · per-app dedicated DB · branched preview DBs

API layer

Server Actions · zod validation · row-level filtering · role checks server-side

Responsive frontend

Mobile, tablet, desktop · accessible components · dark/light surfaces

Per-feature Playwright tests

One end-to-end test per requirement · results captured in the build record

CI + Vercel deployment

GitHub Actions on every push · Vercel preview per branch · production on main

Audit trail

Every state change writes an immutable AuditEvent · queryable by entity, actor, time

Generated artifacts

PDFs, packets, exports rendered server-side · stored in Vercel Blob when needed

Background jobs

Vercel cron · scheduled rollups · SLA timers · escalation rules

the hidden differentiator

Your developers continue building on this.

Your engineers continue from where the ustack Autobuild™ pipeline left off. Most AI-built code is throwaway because the next engineer can't extend it — uStack ships a clean repo on a stack any senior engineer already knows. Day one for your team looks like joining a well-maintained codebase, not reverse-engineering a generation artifact.

// no rebuilds when you outgrow the foundation
Multi-tenant, SSO, on-prem, agentic workflows — all extend the same code. The free build and the multi-week custom build share the same scaffolding.
designed to scale

The foundation handles real load.

Per-app dedicated Postgres. Edge + serverless compute. Framework-native caching. No exotic dependencies, no proprietary runtime to outgrow.

// data

Per-app dedicated Postgres

No co-mingling of customer data. Branch-per-env for safe change requests. Postgres scales linearly with your usage.

// compute

Vercel Functions · Edge

Serverless by default — pay for what runs. Edge functions for low-latency reads. No infra to manage.

// cache

Framework-native caching

Next.js route + data caching. Postgres connection pooling via Neon. CDN for static assets.

// observability

Logs, traces, audit

Vercel runtime logs. Audit events for state changes. Cost guards on long-running jobs.
