Members upload AI illustrations, AI photos and AI manga, tag them, and share the prompts behind each piece, so the site doubles as a living prompt library that anyone can search by model or tag. Beyond the gallery, the platform offers its own in-browser generation tools. Users can create images directly with models such as Stable Diffusion, Stable Diffusion XL, niji-journey, NovelAI, FLUX, ChatGPT and DALL-E-style engines, and the site periodically opens limited-time models through its 'UL' generation feature. A model marketplace, the 'Magoroku Library' of prompt guides, and the chichi-pui shop round out the ecosystem. The service is run by a Japanese operator and monetised through in-site coins and monthly plans, with community activities such as user-hosted posting events, themed collections and daily/weekly/monthly rankings keeping engagement high. It is free to browse and post, with paid elements for extra generation and shop purchases. **Pricing & Plans:** Free to browse and post; paid elements include in-site coins, a monthly subscription plan (reintroduced in October) and shop/marketplace purchases. - **AI image posting gallery:** Upload and browse AI illustrations, photos and manga across illustration, photo and manga sections. - **Prompt (jumon) sharing and search:** Every post can carry its prompt text, and visitors can search prompts by tag or by which model produced the image. - **Built-in AI image generation:** Generate images in the browser with Stable Diffusion, SDXL, NovelAI, niji-journey, FLUX and other supported models. - **Limited-time UL models:** Fresh models are periodically opened through the UL generation feature for a limited period. - **Rankings, events and shop:** Daily/weekly/monthly rankings, user-hosted posting events, a model marketplace and the chichi-pui shop. **Strengths:** Huge, highly active gallery with prompts attached to most posts; Generation tools and a prompt database live in the same place; Rich community features: events, collections, rankings and comments; Free to browse and post, with paid extras only when you want them **Limitations:** Interface and content are primarily Japanese; The most advanced generation models are gated behind coins or a subscription; Some categories contain mature or adult-oriented artwork [Profile (Markdown)](https://openaitools.app/tool/chichi-pui-com.md) ## Code Arena Code Arena is built for developers who want evidence rather than marketing claims when choosing a coding model. Instead of reading benchmark tables, you prompt multiple frontier models with the same request, watch them construct web apps and sites in real time, and then judge the output on accuracy, logic, and code quality. The 'battle' format mirrors the popular blind-comparison leaderboard approach, adapted specifically for software generation tasks. The platform is designed to handle multi-file projects rather than single snippets, so the comparisons reflect the messy reality of real development work: routing, component structure, styling, and state management all have to hold together. Results are surfaced through a leaderboard so you can see which models are consistently favoured by the community over time. Because the tool is free to use and browser-based, it works well as a quick sanity check before committing a paid subscription or API budget to a particular model, and as a way to keep a finger on the pulse of how fast the coding-model landscape is moving. **Pricing & Plans:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately. - **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side. - **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file. - **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together. - **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers. - **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits. **Strengths:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time **Limitations:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship [Profile (Markdown)](https://openaitools.app/tool/code-arena.md) ## Frequently Asked Questions ### How do chichi-pui and Code Arena compare in monthly traffic? chichi-pui has 9,091,626 monthly visits, while Code Arena has 35,827,928.
