No-code tools split by what you're building: full web applications (Bubble, Lovable, Bolt), internal tools on top of your existing data (Retool, Softr, Glide), operational databases (Airtable, Notion), and forms (Typeform, Tally). Bubble remains the most powerful for complex app logic, while newer AI-driven builders like Lovable and Bolt let you describe what you want in plain language.
