## Layout

Layout takes a natural-language brief and turns it into a running full-stack application. The builder understands what you describe, then produces a functional codebase using a modern stack: interactive frontend UI plus a backend powered by Supabase for Postgres storage, authentication and real-time data sync. The output is not a static mockup — it is an app you can click through, extend and deploy.

Because the whole project is editable through both a visual canvas and the underlying code, Layout straddles the no-code and pro-code worlds. Founders can tweak layouts and copy without touching a file, while engineers can export the entire project, push it to their own repository, or continue development locally. The v2 release emphasises faster generation with better structural results.

Connectivity is the other half of the story: Supabase supplies instant auth and real-time databases, Stripe handles monetisation so an app can start accepting payments without custom integration code, and GitHub sync is on the roadmap so generated output stays aligned with professional CI/CD workflows. Hosting is included under a Layout domain, with custom domains and team collaboration flagged as coming soon. A free tier with limited generation credits lets you evaluate the builder before upgrading.

**Pricing & Plans:** Freemium. A free tier provides limited generation credits so you can explore the platform; paid plans unlock more features and higher usage. Exact plan prices are published on the Layout pricing page.

- **Prompt-to-app generation:** Describe your idea in chat and Layout produces a working codebase with frontend UI, routing and project structure rather than a static mockup.
- **Supabase-backed backend:** Managed Postgres, instant REST and GraphQL APIs, real-time sync over WebSockets, built-in authentication and row-level security come out of the box.
- **Stripe payments integration:** Connect a Stripe account in seconds to accept one-time purchases, subscriptions or tiered memberships without writing payment code.
- **Code export and ownership:** Export the entire project codebase to continue development locally or host it anywhere, so you are never locked into the platform.
- **Built-in hosting:** Deploy finished projects instantly on a Layout subdomain with no server setup; support for custom domains is in development.

**Strengths:** Generates a genuinely full-stack app — database, auth and APIs included, not just front-end markup; Works for non-coders and developers alike thanks to simultaneous visual and code-level editing; Full code export prevents vendor lock-in and lets you host anywhere; Integrations with Supabase and Stripe cover the two most common early-stage needs

**Limitations:** Team collaboration and custom domain support are still marked as coming soon; Free tier credits are limited for heavier experimentation; Not a substitute for engineering review on security-critical production apps

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
