Plans

Whichever plan you're on, you build the same way, on the same stack, with the same database, sign-in and publishing. Where they differ is in credits, models, custom domains and how many people can join. A plan belongs to an organization, so everyone in it shares the same credits, seats and domains.

How the plans compare

Prices are in US dollars. Paying for Pro yearly works out to $16.58 a month, while Max is billed monthly only. Free comes with 3 projects.

What you get on every plan

• WebDIY builds your app as you chat. It asks about your idea, writes the app, runs it in the Preview and checks its own work.
• You can read and edit the code. Open Code to work on any file, or take the code with you using Download Code.
• Your app gets a Postgres database, with sign-up and login for your app's users. See Your app's database.
• You can publish to a free website.diy address, served over HTTPS. Search engines don't list website.diy addresses. See Publish your app.
• Keys & secrets holds up to 100 keys per project, and every publish is checked for your secrets first. See Keys & secrets.
• Your team gets roles: Owner, Admin, Builder, Viewer and Guest.
• An Owner or Admin can add your organization's own Anthropic or OpenAI key, and that maker's model tokens then cost no credits.
• Usage keeps a statement of every credit in and out for the last 92 days, which you can export as CSV.
• Any plan can buy more credits, starting at $5 for 400.

On every plan you can also attach up to 10 files to a message, each up to 10 MB.

How many credits you get

Credits cover WebDIY's work on your app, your app's computer while it runs, and hosting for your published sites. Every plan comes with plan credits, and the daily top-up means you can keep building when they run low.

• On Free, your plan credits reset to 500 at the start of each month (UTC).
• On Pro and Max, they reset to 2,000 or 20,000 when your plan renews. A yearly plan resets them each month.
• On any plan, if your plan credits run out before then, they come back up to 100 at midnight UTC each day.
• Unused plan credits don't carry over. Credits you buy are kept separately. They're spent after your plan credits and don't expire.

How credits work explains what uses credits and what happens when you run out.

Which models you can use

You pick the model for each message in the message box. Free offers 6 models, with DeepSeek V4.1 Flash as the default. Pro offers 13 and Max 14, both with Claude Sonnet 5.5 as the default. You also choose how long the model thinks: Low, Medium, High or Maximum. Your plan sets the highest level you can pick, and some models offer fewer levels.

Owners and Admins can set the organization's default model and choose which models members may use, in Settings, then Models. That's also where they can add the organization's own Anthropic or OpenAI key, under Your own AI keys, with Connect key. That maker's models then run on your key, so their tokens cost no credits, though your app's computer still does. A key also opens up every model and thinking level from that maker, on any plan.

Your plan belongs to your organization

Everything you build belongs to an organization, and so do its credits, people and domains.

• You can have one Free organization.
• If you'd like another organization, say one per client, select New organization, give it a name and choose Pro or Max, then select Continue to payment. It starts once the payment goes through on Stripe.
• Seats count the Owner, members and pending invites. A Guest invited to a single project doesn't take a seat.

Changing your plan

Owners and Admins change the plan on the Billing page and pay through Stripe.

• An upgrade starts right away. You pay for the rest of the current period, and your plan credits rise to match.
• A move to a lower plan waits until the end of the period you've paid for.
• To cancel, select Cancel subscription… in the Billing page's menu. Your plan runs to the end of the period you've paid for, and then the organization moves to Free. If its Owner already has a Free organization, it goes on hold instead until someone chooses a plan. There's no refund for the days in between. Your projects and any credits you bought stay put.
• If your organization moves to Free, its connected custom domains keep serving, but you'll need Pro or Max to connect another one.
