## 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

## Upscale Image (Upscayl)

Upscayl is an online image upscaling and enhancement service found at upscayl.app. The idea is simple: you upload a blurry, pixelated or low-resolution photo, choose how you want it enhanced, and download a sharper, higher-resolution result. The main upscaler accepts JPG, PNG, WEBP and ZIP files up to about 20MB each, processes up to 5 images at a time, and lets you pick an upscale factor of 1x, 2x, 4x, 6x or 8x before downloading in JPG, PNG or WEBP.

Beyond the core upscaler, the site groups a large family of related tools: dedicated Anime, Waifu2x, Real-ESRGAN and SeedVR2 upscalers; a background remover, object remover and watermark remover; DeOldify colorization; an AI photo editor; photo restoration; and a printable, product-image-focused upscaler. That makes it a general-purpose online image workshop rather than a single-purpose button.

Upscayl AI is owned and operated by PixelForge LLC. It sells its own credit packs (starting at $10 for 200 conversions up to $100 for 5,000), with larger batches and higher upload resolutions on higher tiers, and credits never expire. Note that this web service shares the 'Upscayl' name with the well-known open-source desktop upscaler but is a separate, hosted product with its own pricing.

**Pricing & Plans:** Upscayl uses credit packs: Mini at $10 (200 conversions, uploads up to 1000x1000px), Creator at $30 (800 conversions), Pro Pack at $50 (2,000 conversions) and Studio Pack at $100 (5,000 conversions), all one-time purchases paid via Dodo and with credits that never expire. Higher tiers raise batch size to 50-100 images and upload resolution to 4000x4000px. A free tier allows a few images per batch.

- **AI upscaling up to 8K:** AI models analyze the image and reconstruct detail to raise resolution while keeping textures and edges natural rather than artificially sharpened.
- **Multiple enhancement modes:** Purpose-built modes for standard photos, portraits, anime and art, face restoration and scratch restoration let you match the tool to the image.
- **Batch processing:** Upload up to 5 images at once on the free tier, with larger batches available on paid plans for high-volume workflows.
- **Extra editing tools:** Non-destructive cleanup tools include background removal, object removal, watermark removal, colorization, photo restoration and an AI photo editor.
- **Format choice and API:** Save your upscaled image as JPG, PNG or WEBP, and use an API with keys to integrate upscaling into your own apps.

**Strengths:** Free tier to test before buying; Wide range of upscale factors from 1x up to 8x; Specialised modes for photos, anime, faces and scratches; Batch uploads and multiple output formats

**Limitations:** Free tier is limited, and high-volume work requires buying credit packs; Maximum upload resolution is capped below 4000x4000px on the entry plan; Only JPG, PNG, WEBP and ZIP are accepted, so other formats must be converted first; Output quality varies with the source image and chosen model
