Substack vs Mailchimp
Substack and Mailchimp serve fundamentally different use cases. Substack is a publishing platform for writers - it handles subscriptions, payments, and distribution. Mailchimp is an email marketing tool. Substack is easier for individual writers to get started; Mailchimp gives more control and flexibility for businesses.

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.

Common questions
Use Substack if you're a writer who wants to quickly monetize a newsletter without technical setup. Use Mailchimp if you're a business that needs email marketing, not a publication platform. The key difference: Substack owns your subscriber relationship in ways Mailchimp does not.
