## Welcome!

NocoDB is an open source Airtable alternative.

NocoDB works by connecting to any relational database and transforming them into a smart spreadsheet interface! This allows you to build no-code applications collaboratively with teams. NocoDB currently works with MySQL, PostgreSQL, Microsoft SQL Server, SQLite, Amazon Aurora & MariaDB databases.

Also NocoDB's app store allows you to build business workflows on views with combination of Slack, Microsoft Teams, Discord, Twilio, Whatsapp, Email & any 3rd party APIs too. Plus NocoDB provides programmatic access to APIs so that you can build integrations with Zapier / Integromat and custom applications too.
