Appbricx vs the DIY stack.
Vercel, Supabase, Resend and a job runner are good tools. Appbricx is one platform your agent operates end to end.
What the stack does well
Picking the best tool for each job is a sound way to build, and many strong teams do it.
Vercel
Front-end hosting with a preview for every branch, instant rollback and serverless functions, made for Next.js.
Supabase
A mature Postgres backend with sign-in, storage, realtime and row-level security.
Resend
A clean email API, with templates written as React components.
A job runner
Inngest, Trigger.dev and similar tools give background jobs durable steps, retries and a dashboard.
Side by side
Each piece is strong on its own. The cost is in the seams: keys, webhooks, environments and bills to keep in step.
| Dimension | Appbricx | Vercel + Supabase + Resend + a job runner |
|---|---|---|
| Who writes the code, with which model | Your agent (Claude Code, Cursor, Codex, Claude or any MCP client) on your own model subscription, or you in your editor. No built-in AI writes your app. | You or your agent, across four dashboards, CLIs and SDKs, wiring keys, environment variables and webhooks between them. |
| Code ownership and export | Plain TypeScript, React and SQL files. appbricx pull puts them in your repo. Export any time, or self-host the single binary. | Your code in your repo, with each vendor's SDK in it. Leaving one means replacing that piece. |
| Database and access control | Postgres per project, with dev and prod databases. Access rules are SQL row-level security policies in db/access/, which the platform checks. | Supabase Postgres with policies you write. Server code that uses the service key skips them, so that code must check access itself. |
| Testing before release | verify signs in as every role and tries every table, page and action in a real browser before a release. Failures come back with evidence and the fix. | What you assemble: unit tests, Playwright, and clicking through Vercel previews. |
| Environments and rollback | Dev and prod per project, a preview per branch, expand-only migrations, a snapshot before every production change and rollback in one call, with the data if you want. | Vercel previews and instant rollback for code. Database migrations and backups are handled in Supabase, so code and data roll back separately. |
| Workflows and background jobs | Durable workflows in TypeScript on data changes, schedules and webhooks, with step.sleep and step.waitFor. Dry runs list every effect without sending anything. | A separate job runner, connected to the app by events and webhooks. Email through Resend's API. |
| Hosting | Server-rendered pages, actions and workflows on an Appbricx address or your own domain with HTTPS. | Vercel for the front end and functions, Supabase for the database, each with its own regions and limits. |
| Pricing model | A free plan, then flat monthly plans for the apps you run. No AI credits: your agent's model stays on your own bill. A one-time license to self-host. | Four vendors and four bills, each with its own free tier, plans and usage pricing. |
| Email and messages | Email, SMS and notification templates in messages/, with typed variables and previews, sent once from workflows. | Resend for email. SMS and push are further services. |
When to pick which
Pick the DIY stack when
- Your team already runs these services well, and the seams are solved.
- You need something specific from one of them, such as Next.js features on Vercel's edge.
- You want to swap any single piece without touching the others.
Pick Appbricx when
- Your agent should operate the whole app, from schema to rollback, through one connection. Build with your AI agent.
- You want releases tested as every role before they ship, and one call to roll back the code and, if you want, the data.
- You would rather have one bill and one place to look when something breaks.
- You still want plain code you own, and the option to self-host. Build in code.
