The 11 best AI app builders with a database and loginin 2026, and what “built-in” means in each

Capacity turns a plain-language description into a working app: a React front end, a server and its own SQLite database (through Drizzle), published at a capacity.studio address or on your own domain. You change it by chatting and see each change in a preview.

Why pick Capacity

• Every app gets its own database as part of the build; for login, you choose Clerk or Auth0 as an extension, or a Supabase connection.
• Build from Claude, ChatGPT or Mistral through Capacity's connector: your own subscription writes the code, unlimited on every paid plan.
• A full version history, the code as a zip on any paid plan, and Capacity Desktop (macOS and Windows) to push it to your own GitHub.

Watch out for

• Login isn't built in: people can't sign in until you add Clerk, Auth0 or a Supabase connection.
• The web app has no free plan: paid plans start at $25 a month. Capacity Desktop has a free plan with one project.
• A smaller community and template library than Lovable's or Bubble's.

Lovable builds web apps from a chat with a live preview beside it. Lovable Cloud, its built-in backend on Supabase's open-source foundation, is on by default and adds a Postgres database, user login, file storage, realtime and server functions. Ask for login and Lovable generates the sign-up and login pages and protects each user's data with row level security.

Why pick it

• Sign-in by email and password, phone codes, Google, Apple, Microsoft or SAML SSO; Lovable manages Google, Apple and Microsoft, so you need no developer accounts.
• Row level security policies are set up as features are built, and daily backups are kept for about 14 days.
• A full database export, structure and data, including users' accounts and password hashes, so they keep their passwords if you move to Supabase.

Watch out for

• Each message uses credits, and Lovable Cloud usage is billed in credits too once its monthly grant is used.
• You pick the data region (Americas, Europe or Asia Pacific) when Cloud is turned on, and it can't be changed later.

Base44, owned by Wix since 2025, builds the front end, backend, database, user login and payments from a plain-language description, runs the apps on its own infrastructure, and connects to tools like Gmail, Slack, Notion and HubSpot. It makes websites, internal tools, online stores and mobile apps.

Why pick it

• Login, sign-up and password reset pages come built in, with email and password plus Google, Microsoft, Facebook and Apple sign-in you switch on.
• Admin and User roles in every app, more roles on request, and data rules such as Creator Only, where people only see the records they created.
• The lowest entry price for an app builder on this list: Starter is $16 a month billed yearly.

Watch out for

• Private apps, open only to people you invite, need a paid plan, and SSO needs a Business or Enterprise plan.
• Google sign-in shows base44.com on the consent screen unless you use your own Google credentials, from the Builder plan.

Replit Agent builds web and mobile apps from a chat inside a full cloud workspace. Ask for a database and it sets up a managed PostgreSQL database, with separate development and production databases. Ask for sign-in and it wires up Replit Auth, where people sign in with a Replit account, or Clerk Auth, a dedicated Clerk tenant with your own branding and login methods.

Why pick it

• Both login options are provisioned by the Agent, with no separate dashboard sign-up or OAuth keys to copy.
• 20 GB of database storage included per app (50 GB on Pro), and the database restores to any Agent checkpoint.
• Any PostgreSQL client or ORM can connect to the database.

Watch out for

• Replit Auth shows a Replit-branded sign-in page and needs a Replit account; Replit recommends Clerk Auth for customer-facing apps.
• The database bills compute time and storage, and heavier Agent work is billed by effort beyond your plan's credits.

Bolt, from StackBlitz, builds websites and web apps from a chat in your browser. Bolt Cloud, its built-in backend, adds hosting, domains and Bolt Database: Bolt creates a database when the project needs one, with sign-in settings, file storage, server functions and a security audit that flags missing row level security policies.

Why pick it

• Unlimited databases, created automatically when a project needs one.
• Email sign-up with confirmation and leaked-password protection on every plan, plus Google sign-in.
• Export any table as CSV or JSON, and on Pro or Teams claim the whole database into your own Supabase account.

Watch out for

• Sign-up and login may not be added on their own: you ask Bolt for them, and Google sign-in needs OAuth credentials you create in Google Cloud.
• Billing is in tokens, and long fix-and-retry sessions on a large project use them up faster.

Floot builds apps from the AI you already use: add it to Claude, ChatGPT or Cursor as a connector and describe the app. Every project comes with a managed Postgres database, sign-in, file storage and email, hosted by Floot with a live link. Asking for login adds email and password sign-up, password reset and a login page, with an admin account for you.

Why pick it

• Google and Microsoft sign-in are brokered by Floot, so there's no OAuth app to register; Apple, GitHub, LinkedIn, Slack and others work with your own credentials.
• Download the whole database as a pg_dump file on any plan, including Free.

Watch out for

• The database runs on Neon, on AWS in US East, and sleeps after about a minute without queries, so the next request can take a little longer.
• Plans cap building actions per day (100 on Free, 1,000 on Pro) and include a monthly hosting allowance ($10 on Pro, $25 on Power).

Zite builds business apps and workflows on its own database from a description, like "a client management app for my marketing agency". Internal apps use your organization's members and permissions. Apps shared to the web get their own login, by magic link or Google, with SSO on Enterprise. Roles set database permissions by table and action.

Why pick it

• Unlimited users on every plan, which suits tools a whole team uses.
• You decide who can sign up: invite only (the default), anyone, or only the email domains you allow.
• Each table exports to CSV, and imports take up to 250,000 records at once from CSV, Excel, Google Sheets or Airtable.

Watch out for

• Records and workflow runs are capped per plan: 5,000 records and 1,000 runs a month on Free.
• Monthly credits cap how much you build: 50 on Free (10 messages a day), 100 on Pro, 400 on Business.

Tadabase AI is Tadabase's new builder: you describe the app your business needs, it asks follow-up questions, then builds the database, logins, permissions, workflows, emails, PDFs and hosting on Tadabase's platform. It generates React code you own, and Claude Code connects to it in one command. Existing customers keep their original Tadabase plans.

Why pick it

• Unlimited app users on every plan, which suits portals with many clients.
• What a portal needs is already built: database, logins, permissions, workflows, emails and PDFs.
• A free plan to start, with a one-time 300-credit welcome bonus.

Watch out for

• Starter publishes 3 apps ($9 a month for each extra one) with 25,000 records per app; external sources like Airtable or HubSpot start on Business, $250 a month.
• Always-on hosting starts on Pro.

Softr is an AI app builder for business operations: secure internal tools and client portals with databases, workflow automation and integrations included. You build with AI or with no-code blocks, and connect data from its own databases or tools like Airtable and Notion.

Why pick it

• Email and password on every plan; one-time codes, Google sign-in and granular permissions from Pro.
• User groups decide which pages, blocks and records each person sees, with global data restrictions on Business.
• The data can stay where it is: Softr Databases, Airtable, Google Sheets, Notion or HubSpot, or PostgreSQL, MySQL and SQL Server on Business.

Watch out for

• App users are capped per plan: 5 on Free, 5 team plus 5 client users on Basic, 10 plus 50 on Pro, 30 plus 100 on Business.
• SSO (SAML or OpenID) is on Enterprise, or a paid add-on on Business.

Glide is an AI app builder for internal business apps: you describe the tool, and Glide builds it on its own platform with integrations and workflows, then publishes it to your team or, from Plus, to the public. You choose how hard its agent works (light, medium or heavy).

Why pick it

• Apps are private to your company by default, and admins control access with roles from Pro and SSO on Enterprise.
• Each project has one database shared by all its apps, built from a spreadsheet, a file or a prompt, and every table exports to CSV.
• A free plan with 10 projects to try it.

Watch out for

• Publishing needs a paid plan, Basic apps are limited to your organization's members, and public apps with sign-in start on Plus at $50 a month.
• Published apps are capped below Pro: 2 on Basic, 5 on Plus.

Bubble is the long-standing visual app builder. It now starts from an AI prompt and lets you switch between prompting and editing visually, for web, iOS and Android apps, with its own database and workflows.

Why pick it

• User accounts are built in: sign-up, login and sessions are handled, and passwords are hashed and salted.
• Privacy rules run on the server and can compare each record with the current user, for fine control over who sees what.
• Social logins through Bubble's plugins, or other providers through its API Connector.

Watch out for

• Bubble's privacy editor marks each data type "Privacy rules applied" or "Publicly visible": review every one before real data goes in.
• Importing and exporting CSV files needs a paid plan, and exports skip privacy rules because the app owner runs them.
