Context

Bubble — No-code platform for building custom web apps with workflows and data. It currently costs $32/mo.

A specific Bubble app is often vibecodable now; rebuilding Bubble's editor, workflow engine, plugin ecosystem, hosting, and scaling layer is not.

This brief describes a focused, single-operator replacement for the part of Bubble that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Rebuild the target app directly in code with CRUD, auth, workflows, and hosting rather than cloning Bubble as a platform.

Assemble a working CRUD app from components, forms, and stored records.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Web framework.

Database.

Auth.

Hosting.

Product-specific integrations.

Data and integrations

Payment/email APIs.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build me the app I currently run on Bubble, as plain code I own. Requirements:

First ask me for: the 3-5 core screens, the data types with their fields,

and the single workflow that matters most. Rebuild that app, not Bubble.

Stack: Node + Express + better-sqlite3, server-rendered EJS templates plus

htmx for interactivity. No SPA framework, no build step.

CRUD for each data type: list page with search and filters, detail page,

create and edit forms with validation.

Workflows become plain functions: a form submit updates rows, sends email

via Resend (key in .env), redirects. Scheduled workflows become node-cron

jobs in the same process.

Auth only if people other than me log in: email+password sessions with

bcrypt and a session cookie, no roles unless I named them. If it is just

me, skip auth and bind to localhost.

File uploads go to uploads/, images resized with sharp.

One SQLite file plus a nightly CSV dump of every table, data never trapped.

Out of scope: a visual editor, a plugin system, anything platform-shaped.

The deliverable is one app that deploys with node server.js on a $5 VPS.

README: deploy steps and how to add a field later, the code is the editor

now.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Visual editor.

Workflow builder.

Plugin marketplace.

Hosting/scaling.

Nondeveloper maintenance.

Templates.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Maintain every third-party integration as APIs and OAuth rules change.

Risk

Operational risk. The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: high. No reviewed project implementation is linked yet.

Existing alternatives

Before building, compare these checked options:

Budibase — Custom web apps with data, forms, screens, and automations; design freedom is far below Bubble's

Corteza — A self-hosted business-app suite with records, pages, workflows, charts, and enterprise-grade amounts of configuration

Joget Community Edition — Forms, lists, workflows, and role-aware apps from a product old enough to have survived several no-code fashions

Prior art

Working open-source software you can read, fork, or borrow from before starting:

Appsmith — Open-source low-code builder for internal tools; partial prior art for visual app building
