Agencies searching for an AI app builder are not shopping for a personal prototype tool. They need to ship portals, dashboards and internal tools for many clients, keep client data apart, put work on a client's domain, and either hand ownership over or keep a retainer — without burning a seat for every designer who opens the project.
This page is comparison intent on that agency purchase. It separates an AI app builder from an AI agency website builder, names the delivery tests that matter more than prompt speed, and checks how Base44, Bolt and Lovable present themselves for client work — with plan figures dated 2026-11-06. The wider app-builder versus business-operator split stays on best AI app builders. Backend layers alone are covered in best AI app builder with backend.
If the brief is only a marketing site, start on best AI website builders instead — that is a different shortlist.
App builder for agencies versus agency website builder
Searchers type both "AI app builder for agencies" and "AI agency website builder." The first usually means software clients will log into — portals, CRMs, inventory, booking backends. The second usually means public marketing pages. Confusing them buys a site generator for a product brief, or overpays for full-stack hosting when the deliverable is a brochure.
An agency delivery that needs authentication, a database and roles is an app-builder purchase. Confirm those layers with the two-user persistence test in best AI app builder with backend, then add the agency tests below: isolation between clients, handoff, and who pays for credits after launch.
What agencies should verify before the first client goes live
| Agency need | Pass/fail test | Why it fails in demos |
|---|---|---|
| Client isolation | Two client projects; staff of A cannot open B's data or secrets | One shared workspace with every client's rows in one table |
| Ownership transfer | Documented path to move the app (or workspace) to the client's account | Export is a ZIP of screenshots; production stays on the agency login forever |
| Custom domain per client | Client's hostname with TLS on a published URL you control | Vendor subdomain only, or domain gated behind an enterprise sales call you never finish |
| Seats versus credits | Know whether adding a PM or client viewer changes the invoice | Per-seat Teams math multiplies faster than credit burn on concurrent builds |
| Who maintains day two | Written answer: agency retainer, client's engineer, or scheduled operator | Demo ends at "shipped"; nobody owns incidents, legal pages or spend caps |
| Exit / source | GitHub sync or clone under an account the client can keep | Platform is the only home; leaving means rebuilding |
Three builders agencies actually shortlist (not ranked)
| Product | Agency-facing claim (read 2026-11-06) | Pricing pointer (confirm at checkout) | Agency fit notes |
|---|---|---|---|
| Base44 | base44.com/agencies markets client apps, websites, agents, unified multi-workspace views, roles, ownership transfer, credit delegation and a partner program. Built-in backend, auth, hosting and custom domains are named on the same page. | base44.com/pricing, read 2026-11-06, lists Free (25 message credits/month), Starter $16/mo, Builder $40/mo, Pro $80/mo and Elite $160/mo with prices shown billed annually; FAQ on that page says yearly billing saves 20%. GitHub integration appears from Builder upward on the plan cards. | Strongest public agency packaging of the three: transfer, credit delegation and directory partner path are written for client delivery, not only solo builders. |
| Bolt | bolt.new pricing nav groups Solutions by business type including Agencies (page chrome on bolt.new/pricing read 2026-11-06). Product markets browser builds with website hosting and databases on the same plans. | Free at $0 (1M tokens/month, daily limit); Pro $25/month; Teams $30 per member per month; Enterprise custom — all on bolt.new/pricing read 2026-11-06. Teams adds centralized billing and admin controls; tokens are not shared between members per FAQ on that page. | Fast for sales-call prototypes. Per-member Teams pricing scales with headcount; confirm export and production hosting against each client's stack before you promise handoff. |
| Lovable | lovable.dev, read 2026-11-06, positions end-to-end hosting, authentication, payments and integrations. Pricing FAQ on lovable.dev/pricing the same day says every plan is a workspace with unlimited members, credits shared across invitees, and optional per-member credit limits for admins. | Confirm current Pro, Business and Enterprise dollar (or euro) amounts on lovable.dev/pricing the day you buy — the FAQ page read 2026-11-06 explains credits and seats but the plan table amounts vary by region. Empyre's Lovable comparison recorded Pro and Business at €25 and €50 for a European visitor on 2026-10-14. | Credit-priced workspaces avoid seat math for large delivery teams; still verify project-level transfer, branding removal and client domain before you sell a retainer on Lovable Cloud alone. |
How agency pricing usually breaks
Three invoice shapes show up in the table above. Credits (Base44 messages, Lovable credits, Bolt tokens) spike when several client builds run in parallel. Seats (Bolt Teams at $30/member/month on the page read 2026-11-06) spike when account managers and clients need logins. Enterprise custom quotes hide SSO, audit logs and transfer rules until sales responds.
Before you price a package to a client, map your margin: platform plan + expected credit burn for revisions + whose subscription the live app sits on after handoff. Base44's agencies page, read 2026-11-06, explicitly describes credit delegation so agency credits can fund work inside a client workspace — that is a different cost model than leaving every production app on the agency's Pro seat forever.
Do not invent a "best for agencies" ranking from marketing adjectives. Run one throwaway client brief on each shortlisted tool and score the isolation, transfer and domain rows in the checklist.
Buyer checklist — AI app builder for agencies
Use a real (or anonymised) client brief, not the vendor's sample CRM:
Two fake clients
Create two projects; prove secrets, users and files do not leak across them.
Handoff rehearsal
Transfer or sync to a second account before the contract starts — not after launch week.
Domain on the client's brand
Attach the client's hostname; check TLS and that vendor chrome matches what you sold.
Invoice forecast
Add the people who will touch the build; note whether the bill moves with seats or only with credits.
Post-launch owner
Write who patches dependencies, answers the client's customers, and caps model spend — agency, client, or operator.
Source control
Confirm GitHub sync or export under an org the client keeps if the retainer ends.
Legal and payments
If the app collects data or takes money, know who drafts terms and which Stripe account settles — see legal pages for AI-built businesses.
Red flags on agency pitches
"White label" without a domain path
Logo swap in a demo is not the same as the client's hostname and email.
One workspace for every client
Convenient for the agency; catastrophic when a contractor should only see one account.
Handoff equals PDF
If the client cannot run or host the artifact without your login, you sold a hostage, not a product.
Unlimited client apps on Free
Fine for demos; production traffic, SSO and transfer often sit on higher tiers — read the plan cards dated the day you quote.
Silence on day-two ops
Builders that stop at publish leave incidents to whoever answers the phone — usually you.
Where Empyre fits (once)
Empyre is not an agency white-label reseller console. It is an AI company operator: you describe a business (or import one), and eight scheduled executives build, publish and keep running that company — product, marketing, support, legal surface and spend gates — with customers paying into the founder's own Stripe (or named provider). Published plans are Starter $49, Growth $149 and Empyre $299 per month on empyre.dev/pricing. Choose Base44, Bolt or Lovable when your agency will deliver and maintain (or cleanly hand off) the software. Choose Empyre when the buyer needs the company operated after launch without assembling that roster themselves — including agencies that productise "we stand up an operated business," not only a repo.
Common questions
What is the best AI app builder for agencies?
There is no universal winner. Base44 publishes the most explicit agency packaging (transfer, credit delegation, partner path) on base44.com/agencies read 2026-11-06; Bolt and Lovable are commonly shortlisted for speed and shared workspaces. Score isolation, handoff and invoice shape on your brief before you standardise.
Is an AI agency website builder the same purchase?
Usually not. Website-builder intent is public pages; app-builder intent is authenticated software. Start on best AI website builders only when the SOW is a site.
Do agencies need white-label features?
Only if you resell under your brand or the client must never see the vendor. Many retainers succeed with the client's domain and your agency named in the footer. Ask for the domain and transfer path in writing either way.
How should we price client builds on credit plans?
Estimate revision cycles, not just the first generate. Concurrent clients multiply credit burn; seat plans multiply with staff. Rehearse one full revision loop on the paid tier you will actually use.
When is Empyre the agency-relevant answer?
When the engagement is an operated company rather than a delivered codebase — or when nobody on either side will maintain production after week one. Empyre is the wrong default if you only need a white-label builder UI for dozens of small marketing sites.
