The Dyad AI app builder is a free, open-source desktop tool that turns plain-language prompts into working web apps that run on your own machine. Totalum is a hosted AI app builder that creates a full production app in the cloud, with database, auth, payments, hosting, and a REST API and MCP endpoint included. Both let you describe an idea and get a real Next.js app, but they solve different problems: Dyad gives developers local control and clean exportable code, while Totalum gives founders and teams a production stack that is live the moment it is built. This guide compares the two honestly so you can pick the right one.
Quick Answer
- Dyad is a local, open-source AI app builder you download and run on your desktop. You bring your own AI model keys, and you wire up your own database (Supabase), hosting (Vercel), and deployment (GitHub). Best for developers who want full local control and zero lock-in.
- Totalum is a cloud AI app builder where the database, admin CMS, auth, payments, hosting, and custom domain are built in and live automatically. You can also drive it from any agent via API or MCP, or white-label it. Best for non-technical founders, product teams, and agencies who want production without assembling a stack.
- Ownership: both let you own and export your code. Dyad is open-source and offline-first; Totalum stores data in the EU and lets you download the full Next.js source at any time.
- Pricing: Dyad is free locally, with Dyad Pro at $20/month and Dyad Max at $79/month for hosted AI credits. Totalum has a free tier and paid plans from $29/month, priced per project with hosting included.
- Pick Dyad if you are a developer who wants a local, model-agnostic builder. Pick Totalum if you want a hosted, production-ready app or an app builder you can embed in your own product.
What is the Dyad AI app builder?
The Dyad AI app builder is an open-source desktop application, described on its own site as "the open-source AI app builder on your desktop" that lets you "turn your ideas into web apps without coding." It runs locally, so the tagline "runs on your machine, your data, your control" is literal: the app, your project files, and your prompts stay on your computer rather than in a vendor cloud.
Dyad is model-agnostic. You connect your own API keys for providers like OpenAI, Anthropic, Ollama, and LM Studio, which means you can even run local models offline. The generated project is standard, exportable code, and Dyad markets "export clean, runnable code, no lock-in, ever" plus the ability to "inspect, fork, and extend the codebase" because the tool itself is open-source (the repository is on GitHub at github.com/dyad-sh/dyad).
In plain language: Dyad is like having a coding assistant that lives on your laptop, builds a real web app from your description, and hands you the finished code. It does not host the app for you or run your database. You connect those services yourself.
For developers: Dyad scaffolds a React or Next.js style project and integrates with Supabase for database, authentication, and server functions. It runs a security scan for common issues like SQL injection and cross-site scripting, and it can push to GitHub and deploy to Vercel. You own the whole pipeline, and you also own the ongoing job of maintaining those third-party accounts.
What is Totalum?
Totalum is an AI app builder that creates real, production-grade web apps from a prompt, in the browser. It is a peer to tools like Lovable, Bolt, Replit, and v0, not a hosting layer bolted onto something else. You describe your idea, and Totalum builds the full Next.js application: frontend, backend, database, admin panel, auth, payments, hosting, and a custom domain.
The difference that matters for this comparison is that Totalum delivers the whole production stack assembled and running. There is no separate Supabase project to create, no Vercel account to connect, no model key to manage. Data is stored in the European Union with automatic hourly backups, and you can still open the built-in code editor and download the complete source at any time, so ownership is not traded away for convenience.
Totalum also has two modes that Dyad does not offer. First, it is usable via REST API and MCP, so an AI agent such as Claude, Cursor, or ChatGPT can create and maintain an entire app through Totalum, and a SaaS company can embed the builder in its own product. Second, there is a white-label option that runs the full builder behind your brand and domain. Totalum is independently ranked on the public AI agents benchmark.
From prompt to live app: how the workflow differs
The clearest way to understand the two tools is to walk the same job through each: you describe an app, and you want it live for real users with sign-in and payments.
With the Dyad AI app builder, the flow is local-first and hands-on.
- You download and install the Dyad desktop app, then add an API key for the model you want to use.
- You describe the app in the chat, and Dyad generates the project on your machine, which you can open and edit like any codebase.
- To add data and accounts, you create a Supabase project and connect it, then configure authentication and any server functions there.
- To take it live, you push the repository to GitHub and deploy to Vercel, then point a domain you own at it.
- Payments, email, and any other service are extra integrations you add and maintain yourself.
For developers, that sequence is familiar and gives you total control over each layer. For a non-technical founder, it is several accounts and configuration steps before anything is usable by a customer.
With Totalum, the flow collapses into one place.
- You describe the app on totalum.app, and Totalum builds the full Next.js project in the cloud.
- The database, admin CMS, authentication, and integrated payments are already wired, so sign-in and checkout work without a second service.
- Hosting and a custom domain are included on paid plans, so the app is live as soon as it is built.
- You can open the built-in editor to change anything, and download the complete source whenever you want.
For developers, that means you can still drop into the code, and you can also drive the whole thing programmatically through the REST API or MCP. For a non-technical founder, it means the app is in front of users the same day, without managing infrastructure.
The tradeoff is real and worth stating plainly: Dyad gives you more control over every layer at the cost of assembling and maintaining them; Totalum gives you a running production stack at the cost of not hand-picking each underlying service.

Where the Dyad AI app builder wins
Dyad is the stronger choice in a few clear situations, and it is worth being honest about them.
Local-first privacy and offline work. Because Dyad runs on your machine and can use local models through Ollama or LM Studio, you can build without sending prompts or code to a hosted service. For developers with strict privacy needs or spotty connectivity, that is a genuine advantage.
Model choice and cost control. Bringing your own keys means you decide which model handles each request and you pay providers directly. If you already have credits or a preferred model, Dyad lets you use them.
Open-source transparency. The tool itself is open-source, so you can inspect how it works, fork it, and extend it. Teams that require auditable tooling or want to self-modify the builder will value this. Dyad is featured in our roundup of open source AI app builders and self-hosted alternatives for exactly these reasons.
You like assembling your own stack. If wiring Supabase, Vercel, and GitHub yourself feels like control rather than chore, Dyad fits your workflow.
Where Totalum wins
Totalum wins whenever the goal is a live, production app rather than local code, or when the builder itself needs to be part of a product.
Nothing to assemble. With Dyad you get code, then you still create a Supabase project, connect Vercel, buy a domain, and manage AI keys before anything is truly live. With Totalum the database, auth, payments, hosting, and domain are already wired and running. A non-technical founder can go from prompt to a working, payable app without touching a second service.

Built for non-technical builders. Dyad expects you to be comfortable with local dev tooling. Totalum is designed so someone without an engineering background can ship, which is why founders coming from Bubble, Webflow, Glide, and Softr often land here. See how it stacks up in our overview of the best AI app builder in 2026.
Usable by agents and embeddable in products. This is the biggest gap. Totalum is the first AI app builder you can call from any backend through REST API or MCP. Your AI agent can build and maintain a full app through Totalum, and a SaaS company can embed a "describe your idea, get an app" feature, or clone a Lovable-style builder under its own brand. Dyad has no API or MCP path and no white-label mode.
Production data handling. Totalum keeps data in the EU with hourly backups and a built-in admin panel, so the operational side is handled rather than left to you. Teams evaluating Dyad against hosted, no-lock-in options often shortlist Totalum as a Lovable alternative in 2026 too.
Pricing compared
Pricing works differently because the products are structured differently.
Dyad is free to download and use locally with community support. Paid tiers add hosted AI credits and pro features: Dyad Pro is $20/month with 200 AI credits and modes for larger codebases, and Dyad Max is $79/month with 900 AI credits and office-hours access. Remember that with the free tier you still pay your model provider and any hosting or database services separately, so the real cost is Dyad plus the stack you assemble.
Totalum has a free tier with 50 credits per month, then Starter at $29/month, Business at $59/month with deploy, hosting, and custom domain, Professional at $99/month, and Enterprise from $299/month. Pricing is per project and includes the hosting and database, so there is no separate infrastructure bill to add on. The API and MCP path is a separate sales conversation.
The honest read: for a hobby project you keep entirely local, Dyad free is hard to beat on price. For anything you need live in front of real users, compare Totalum's all-in price against Dyad plus Supabase plus Vercel plus model costs before deciding.
Which AI app builder should you choose?
Choose the Dyad AI app builder if you are a developer who wants a local, open-source, model-agnostic tool, you are happy to connect and maintain your own database and hosting, and privacy or offline work matters to you.
Choose Totalum if you want a production app without assembling a stack, if you are non-technical or moving fast, or if you need something Dyad simply does not offer: an app builder you can drive from an AI agent via API or MCP, embed inside your own SaaS, or run white-label under your brand. Agencies delivering client work and SaaS teams embedding a builder are squarely in Totalum's lane.
Many teams even use both: Dyad for quick local experiments, Totalum when a project needs to go live and be maintained in production. They are not strictly either-or.
FAQ
Is the Dyad AI app builder free?
Yes, Dyad is free to download and use locally with community support. Paid plans (Dyad Pro at $20/month and Dyad Max at $79/month) add hosted AI credits and pro features. With the free tier you still pay your own AI model provider and any database or hosting services you connect.
Does Dyad host my app or is it local only?
Dyad runs on your desktop and generates code locally. It does not host your app for you. You deploy it yourself, typically to Vercel, and connect your own database through Supabase. Totalum, by contrast, includes hosting, database, and a custom domain so the app is live automatically.
Can I own and export my code with either tool?
Yes. Dyad is open-source and lets you export clean, runnable code with no lock-in. Totalum is not open-source but gives you a built-in code editor and lets you download the full Next.js source at any time, so you own your code either way.
Can an AI agent use Dyad or Totalum through an API?
Only Totalum. It is the first AI app builder usable via REST API and MCP, so an agent like Claude, Cursor, or ChatGPT can create and maintain a full app through it. Dyad has no API or MCP integration and is driven from its desktop interface.
Which is better for a non-technical founder?
Totalum, in most cases. It ships the database, auth, payments, hosting, and domain already wired, so a founder without an engineering background can go from prompt to a live, payable app. Dyad assumes comfort with local development tooling and self-managed services.
Ready to build with Totalum?
If you want a real production app without wiring up a separate database, host, and payment provider, you can start free. Create your first app at totalum.app, describe your idea, and get a full Next.js application with everything included. If you are a SaaS team or agency that wants to embed or white-label the builder via API and MCP, that path is available too.
