Side-by-side capabilities.
Scored 1–5, integers only. Notes explain the score when the raw number would feel unfair without context.
| Capability | Lovable | Duet |
|---|---|---|
| Builds web apps from natural language | 5/5 Best-in-class build UX — previews, iteration, deploy-on-save. | 4/5 Strong build flow, but optimised for build + ongoing operate. |
| Hosts what it builds | 5/5 Native Lovable hosting; custom domains on paid plans. | 4/5 Hosts on Duet subdomains or custom domains from your workspace. |
| Runs scheduled operations after build | 1/5 Not a Lovable lane — operations belong to other tools. | 5/5 Crons, triggers, and long-running workflows are first-class. |
| Persistent memory across sessions | 2/5 Remembers within a chat; not across the business. | 5/5 Workspace memory survives across sessions, files, and teammates. |
| Private isolated workspace | 1/5 Generated-app platforms make isolation worth reviewing. | 5/5 Every workspace runs on its own isolated cloud server. |
| Team-native collaboration | 4/5 Workspaces 2.0 brings unlimited collaborators on Pro. | 5/5 Team-native by design — shared sessions, files, and apps. |
| Scoped business integrations | 3/5 Solid first-party + Zapier reach for build-time integrations. | 5/5 Duet can connect many tools through managed integrations, APIs, webhooks, and custom setup depending on credentials and permissions. |
| Mobile + desktop apps | 4/5 iOS + Android shipped May 2026; voice "vibe-coding" focus. | 4/5 iOS + Android shipped May 2026; tuned for team collaboration. |
| Operate recurring business workflows | 1/5 Build is the product; ops is your problem. | 5/5 One workspace handles build + run + remember. |
Where Lovable wins.
Credit where it's due. If your job lives in one of these rows, the right answer is Lovable.
App generation polish
Lovable's UI for “describe an app and watch it build” is best-in-class. The previews, the iteration loop, the deploy-on-save flow — it's faster than Duet for pure web-app generation.
Mobile-first builder
Lovable's iOS and Android apps (shipped May 2026) let you vibe-code from your phone with voice. Duet has mobile apps too, but they're for collaboration with your AI coworker, not for building from scratch on a phone.
Onboarding for first-time builders
Lovable's templates and starter prompts are tuned for “I've never built anything” users. Duet assumes you already have a small business to run, so the on-ramp is shaped for operators rather than absolute first-time builders.

Where Duet wins.
The honest difference is what happens after you ship.
Lovable is build-first. Duet builds and runs.
Lovable's job is over at deploy — your app is now your problem to operate. Duet's job starts at deploy: the same workspace that built the app triages the support inbox, sends scheduled reports, integrates with Stripe and Shopify and your CRM, patches bugs you spot, and builds the next app that depends on it.
Your own private server, not shared infra
After public security concerns around generated-app platforms in 2026, infrastructure isolation matters when customer data lives inside generated apps. Duet gives every workspace its own isolated server — customer data, conversations, and code are not pooled into a shared app-builder environment.
Persistent memory that compounds
Lovable remembers your prompts within a chat. Duet remembers everything across sessions, across team members, across months — the coworker that built your customer dashboard in March remembers in October why you made that one weird design choice and what the customer feedback was. That's the difference between an AI tool and an AI coworker.
Team-native by default
Lovable Workspaces 2.0 (Pro plan) gets you unlimited collaborators on a build-centric surface. Duet is team-native by design — humans and your AI coworker share sessions, files, apps, and context, with every run preserved as a visible event history. For agencies and small teams where the AI is the third employee, not the eleventh tool, the workflow shape is fundamentally different.
Real-world scenarios.
We don't compare list prices — those change. Here's what each tool actually costs in three common situations.
Freelance consultant, one app + ops
LovableLovable’s paid builder plan can cover the app build, but inbox triage, scheduling, CRM work, and automation glue live in separate paid tools.
DuetDuet has monthly plans with included credits and reserve overage. Check current pricing against the workflows you want it to own.
5-person marketing agency
LovableLovable’s team builder plan plus the usual operating stack can make sense if build speed is the only bottleneck; the operating layer still sits elsewhere.
DuetDuet can consolidate parts of that operating layer into one AI coworker workspace, so compare the current plan against the tools it would replace.
One-off MVP, never touching it again
LovableA focused app builder is the cleaner buy when you only need a short build sprint and no recurring operations.
DuetDuet is overkill for a true one-off — use the focused builder and check current pricing before deciding.
From Lovable to Duet.
If your Lovable app has outgrown a build-only workflow, the move to Duet is straightforward.
Export your app's source code from Lovable
Use the Pro-plan export option to pull the full repo down to your machine. You'll keep ownership of the code regardless of where it lives next.
Push it to a new Duet workspace
Spin up a Duet workspace, point it at the repo, and let your AI coworker bring the project online inside its own private cloud server.
Wire up the cron, inbox, and Slack triggers
Hand Duet the ops jobs you wanted Lovable to run — scheduled reports, support triage, customer follow-ups — and Duet turns them into reviewed queues, scheduled reports, and explicit approval rules.
Hand the workspace to your team
Invite teammates into the workspace so humans and the AI coworker share sessions, files, apps, and history.
Pick by the role you actually play.
Every comparison still depends on who's asking. Jump into the persona axis to see the work each role hands off first.
- I'm a solopreneur
Duet — one workspace builds the site, runs the inbox, and ships the apps you never finish.
- I run an agency
Duet — keep client work isolated per workspace and let the AI coworker absorb the production layer.
- I run a service business
Duet — prepare appointments, invoices, payment follow-ups, and review requests with approval rules.
- I run small ecommerce
Duet — draft product pages, run support, and recover abandoned carts from one workspace.

Common questions about Duet vs Lovable.
Is Duet a Lovable competitor?
Partially. We overlap on "build apps from natural language," but the real Duet product is the full operate-your-small-business workspace. Lovable is a builder. Duet is a teammate.
Can Duet build apps as fast as Lovable?
For typical CRUD-style business apps, yes. Lovable is faster on the polish of the build UX. Duet can be faster for workflows that need ongoing operations because it doesn't hand you an operations problem at the finish line.
Is Lovable security scrutiny a real concern for small businesses?
If you store customer data in a generated app, the underlying infrastructure model matters. Duet's per-workspace isolation is built to reduce the blast radius of shared-infrastructure risk.
Can I use both Lovable and Duet?
Yes. Some users prototype in Lovable, then move production builds to Duet for ongoing ops. That's a totally reasonable pipeline — Lovable for the build sprint, Duet for the years afterward.
Can I try Duet before subscribing?
Yes. Start with a 7-day free trial, then choose Starter, Pro, or Max to keep running charged work. Each monthly plan includes credits.
What if I just want to vibe-code on my phone?
Use Lovable. Their mobile builder is purpose-built for that. Duet has mobile apps, but they are tuned for collaborating with your AI coworker on running work, not for building from scratch on a phone.
How is Duet different from Lovable plus Zapier plus ChatGPT?
That stack introduces more moving parts: separate memory, separate automation logic, and multiple vendors to coordinate. Duet keeps the work in one workspace with one teammate that remembers what you have already done.
What about pricing for high-usage teams?
Duet offers monthly plans with shared included credits. Adding humans to the workspace does not multiply the subscription the way SaaS seat pricing does; reserve topups cover overage.
Can my AI coworker access my Lovable-built app?
Yes — once you migrate it into a Duet workspace, your AI coworker can operate the app, monitor it, and extend it. Duet can connect external services through the integration path you enable, depending on credentials and permissions.
Is Duet open source?
Some surrounding developer tooling is open source. The Duet web product and managed control plane are closed-source SaaS hosted on Duet infrastructure.
Will Duet replace developers?
For solo founders and small businesses, Duet can cover many internal SMB tools. Complex production systems still need developers; your AI coworker is a force multiplier, not a replacement.
How do I get started with Duet?
Sign up at duet.so, point Duet at your business URL, and start with one connected workflow. The first useful output depends on the workflow and tools connected.
Build with Lovable, run with Duet.
Or skip the round-trip — hire your first AI coworker now, hand them the next app, and let them keep the lights on after launch.
