Adalo is a no-code platform for building native mobile and web applications using a drag-and-drop visual canvas backed by a hosted PostgreSQL database, without writing code. It recently added Ada, an AI assistant (in beta) that helps generate app screens and logic from natural-language prompts alongside the traditional visual builder. Plans scale from a free tier for building and testing to a Starter tier unlocking web publishing and automated App Store submission, up through Professional and Team tiers adding custom integrations, geolocation, push notifications, and white-labeling. Adalo differentiates itself with flat-rate pricing that does not scale with the number of app users, records, or actions, making costs predictable regardless of app growth.
Sleek is an AI-powered mobile app designer that lets users go from idea to polished iOS and Android app designs in minutes by chatting with AI. It generates complete screens with layout, components, copy, and styling, and offers visual editing, templates, and one-click export to Figma or code (HTML/React with Tailwind CSS). It also provides an API and agent skill for use with AI coding agents like Claude Code, Codex, or Cursor.
Sleek offers a free plan with 60 one-time credits, plus paid subscription plans starting at $39/month for Starter, $69/month for Pro, and $99 per seat/month for Team, with annual billing options available.
- Flat-rate pricing means costs do not scale with users or usage
- Automated app store publishing removes a common no-code pain point
- Free tier includes a real hosted database, not just a mockup
- AI assistant speeds up initial screen and logic generation
- No design experience required; built for founders, PMs, marketers, and developers
- Generates complete, high-fidelity mobile app screens from a simple text prompt or reference image
- Mobile-specific design conventions (iOS HIG, Material Design, native navigation, accurate device dimensions)
- Visually edit and iterate designs quickly without needing Figma skills
- Native app store publishing requires a paid plan starting at $36/month
- Fewer app editors on lower tiers can bottleneck small teams
- Advanced integrations like Xano require the highest-priced Team plan
- Free plan is very limited (60 one-time credits, 1 project, 3 screens)
- Paid plans are subscription-based and may be costly for casual users ($39-$99/month or $240-$490/year)
- AI-generated designs may still require manual refinement for complex or highly custom needs
- Primarily focused on mobile app design, not suitable for web or desktop UI design

The Verdict
AI-generated from listing dataSleek excels at AI‑generated, high‑fidelity mobile UI design with export to code, while Adalo is a full no‑code app builder that includes hosting, databases, and app‑store publishing.
Key differences
- •AI design generation vs. drag‑and‑drop app building
- •Export to Figma/HTML/React (Sleek) vs. built‑in hosted PostgreSQL and publishing (Adalo)
- •Pricing model: credit‑based subscription tiers (Sleek) vs. flat‑rate plans with unlimited usage (Adalo)
- •Target focus: mobile UI mockup/design (Sleek) vs. end‑to‑end app creation including backend (Adalo)
- •Collaboration features limited to paid tiers in Sleek; Adalo offers team features and version history in higher plans
Pricing & value
Adalo’s flat‑rate plans have no usage caps; Sleek’s credit system can become costly for heavy design use.
Ease of use / learning curve
Sleek creates complete screens from text prompts, requiring no design skill; Adalo still needs canvas layout work.
Features & depth
Adalo provides database, hosting, and app‑store publishing; Sleek focuses only on UI design and code export.
Integrations & ecosystem
Adalo lists integrations (Xano, Stripe, Zapier) and API; Sleek mentions AI coding agents but no third‑party app services.
Collaboration
Adalo offers version history and white‑labeling for teams; Sleek’s collaboration is limited to paid plans.
Scalability
Adalo’s hosted backend scales with app usage; Sleek’s credit limits may restrict large‑scale design projects.
Support
Adalo provides email support and priority support on Team plan; Sleek’s support details not specified.
Choose Adalo if…
Non‑technical founders needing an all‑in‑one no‑code platform that hosts data, publishes to app stores, and scales with users.
Choose Sleek if…
Founders or PMs who need fast AI‑generated mobile UI mockups and code export without building a full backend.
Common questions
Can I export my design from Adalo to code?
Not specified; Adado focuses on visual app building and publishing, not code export.
Does Sleek include a backend or database?
No; Sleek provides design generation and export, but no hosted database or app‑store publishing.
Which tool is cheaper for a small team that only needs a few mobile screens?
Sleek’s free plan offers 60 credits and 3 screens; for minimal design needs, it may be cheaper than Adalo’s paid plans.
