Context

**Coda** — Doc platform that combines writing, tables, automations, and small apps. It currently costs $12/mo.

A doc with tables and buttons is buildable; Coda's editor, formula engine, packs/integrations, permissions, and team workflows make full parity difficult.

This brief describes a focused, single-operator replacement for the part of Coda 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

Build a rich doc editor, embedded tables, formulas, buttons, and simple automations.

Build a focused single-user workflow with real persistence, search, and export.

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

Requirements

Functional

Rich text editor.

Database tables.

Formula engine.

Auth.

Integrations.

Hosted backend.

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 a docs-with-tables workspace to replace Coda, single-user.

Requirements:

Local web app: Node + Express + better-sqlite3, server-rendered pages with

vanilla JS, no build step.

Docs are Markdown edited in a textarea with live preview (marked); a

fenced block naming a table, like table:Expenses, renders that table live

inside the doc.

Tables have typed columns (text/number/date/select/checkbox), inline row

editing, and are real SQLite tables I can query with other tools.

Formula columns: a JS expression over the row's other fields (price * qty)

evaluated server-side with new Function over plain values only, recomputed

on edit. No imports, no network access in formulas.

Buttons in docs: a doc can declare a button that runs one whitelisted

server action (add row with defaults, mark done); docs never execute

arbitrary code.

Named views per table: filter + sort saved and embeddable in any doc.

CSV export per table, Markdown export per doc; localhost only, no

accounts, no telemetry.

Out of scope: collaboration, permissions, and packs/integrations. Coda's

formula language and pack ecosystem are the product; this is my personal

version.

README: setup and where the data lives on disk.

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:

Formula language.

Packs.

Permissions.

Automations.

The last 20 percent is sync, migration fidelity, speed, and edge cases.

Permissions, presence, and shared workflows are difficult to simplify.

What you still own after launch

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 independent one-shot implementation is linked yet.

Prior art

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