AppSheet

Glide

Glide is a no-code platform that turns spreadsheets and databases, including Google Sheets and SQL sources, into functional web and mobile apps without writing code. Users connect a data source, then use Glide's visual builder to design app layouts, forms, and workflows that read from and write back to the underlying data automatically. Apps built with Glide are mobile-responsive by default and can also run on Glide's own built-in database when an external spreadsheet is not needed. Pricing is credit-based across Free, Solo, Team, and Enterprise tiers, and the platform is aimed at small businesses and internal-tools teams who want to turn existing operational data into a usable app fast, without a native app-store publishing path.

Softr

Softr is a no-code platform for building custom business applications, internal tools and client portals without writing code. Users can describe what they need in plain language and have AI generate the interface, database and workflows, or assemble apps manually with a built-in database, forms and automation features. Softr connects to 30+ external tools including Airtable, Notion, HubSpot and Slack, and includes built-in AI agents ('Ask AI') that can operate autonomously inside an app. It reports being used by over 1 million teams, with published customer logos including Make, the NBA, Google, Netflix and UPS.

Appsmith

Appsmith is an open-source low-code platform that empowers developers to build custom internal tools quickly and efficiently. With a drag-and-drop interface and a vast library of pre-built components, Appsmith streamlines the development process, allowing teams to focus on high-priority tasks. The platform is highly customizable, scalable, and integrates seamlessly with popular services like Google Sheets, PostgreSQL, and more.

Adalo

Adalo is a no-code platform for building native mobile and web applications using a drag-and-drop visual canvas backed by a hosted PostgreSQL database, without writing code. It recently added Ada, an AI assistant (in beta) that helps generate app screens and logic from natural-language prompts alongside the traditional visual builder. Plans scale from a free tier for building and testing to a Starter tier unlocking web publishing and automated App Store submission, up through Professional and Team tiers adding custom integrations, geolocation, push notifications, and white-labeling. Adalo differentiates itself with flat-rate pricing that does not scale with the number of app users, records, or actions, making costs predictable regardless of app growth.

ToolJet

ToolJet is a low-code platform for building internal business applications, automation workflows, and AI agents using a visual drag-and-drop builder combined with natural-language prompting. It connects to databases, APIs, and 80+ third-party services, and includes ToolJet Database, a built-in PostgreSQL-based no-code data store with a visual table and join builder. Beyond app building, ToolJet offers workflow and agent automation for scheduled or event-triggered business processes. It is available as a managed cloud service or self-hosted on-premise or in AWS, Azure, GCP, and air-gapped environments, and holds SOC 2 Type II, ISO 27001, and GDPR compliance, with enterprise features like SSO/SAML, RBAC, and audit logs on higher-tier plans.
