How Appaca works
Appaca is not another SaaS tool to evaluate. It builds you a working app from a plain description — with database, dashboards, and team access — and runs it on the platform.
Describe what you need
Tell Appaca what you need in plain language. No forms, no setup wizard — just describe the job to be done.
Chat with AI to refine it
Appaca AI builds your app and stays available to refine it. Change behaviour, add fields, adjust flows — all in chat.
Use it immediately
Your app runs on Appaca with a built-in database, file storage, and team access. No deployment, no devops.
Everything your team needs, built in
Appaca provides the full stack for internal and personal software — no integrations to wire up, no hosting to manage.
Build and update apps by chatting with AI
Describe what you need and Appaca builds a working app. Come back any time to refine it — add new fields, change behaviour, or extend functionality — all without writing code.
Built-in database and file storage
Every Appaca app comes with a secure database and file storage ready to use. No external service to connect, no schema to design — Appaca handles the data layer automatically.
Connect to services your team already uses
Appaca apps can connect to Google Sheets, Slack, Airtable, and any service that supports an API or webhook — so your app fits into your existing workflow instead of replacing it.
