## 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

## sampleapp.ai

sampleapp.ai attacks a familiar developer-marketing problem: prospects often abandon an integration before they ever make a successful call, because they are left alone with documentation, Postman tabs and snippets that do not match their stack. The platform replaces that with a Stripe-style guided experience — steps on the left, a live preview in the top-right and generated code at the bottom-right, all kept in sync as the developer progresses.

Flows are personalised per prospect: pre-built flows for their specific use case, code snippets in their own framework, and their own API keys and environments, all running in the browser with no local setup. Your team gets a dashboard that tracks who started, who is stuck on which step and who finished, plus time-to-first-call metrics broken down by use case.

It is aimed squarely at developer-focused companies — API platforms, SDK vendors, infrastructure startups — and their DevRel, solutions architect and sales engineering teams. The site reports metrics such as reducing integration time from about two weeks to four hours and cutting support tickets by 80%, positioning SampleApp as an onboarding and activation layer that sits on top of documentation rather than a replacement for it.

**Pricing & Plans:** Contact for pricing. The site offers a free start alongside a Request For Preview form for getting a tailored walkthrough, and a Book a Demo option for teams evaluating a rollout. Enterprise and team pricing is quoted directly by the vendor rather than published on the pricing page.

- **Stripe-style guided onboarding:** Move past static docs with pre-built, interactive flows tailored to each prospect's specific use case, so developers see exactly how your API fits their problem before writing much code.
- **Synced steps, preview and code:** The walkthrough shows steps on the left, a live preview top-right and generated code bottom-right, all synced as the developer advances — with snippets produced in their actual tech stack using their own API keys and environment.
- **Progress dashboard for your team:** Track who started the integration, who is stuck and who finished, measure time-to-first-call by use case, and be notified when prospects complete key steps — turning developer onboarding into a measurable funnel.
- **Framework and docs embedding:** Guides can be generated in the frameworks your prospects use — React, Vite, FastAPI, Flask, Express and Go — and embedded in Docusaurus, Fern, Mintlify, ReadMe or GitBook with a short snippet.
- **CRM and GTM integrations:** Progress analytics sync with sales and go-to-market tools such as HubSpot, Salesforce, Common Room and Reo.dev, so DevRel, sales engineers and customer success can act on the same signal.

**Strengths:** Turns static API docs into an interactive, copy-ready integration experience; Generates snippets in the prospect's own framework with their own keys and environment; Gives DevRel and sales engineering measurable drop-off and activation data; Embeds into popular docs platforms and syncs with common CRM and GTM tools

**Limitations:** Focused on API/SDK onboarding rather than general-purpose app generation, so it is not a fit for non-API projects; Enterprise-style pricing needs a conversation with sales, so cost is not transparent upfront; Value depends on your prospects actually running the guided flow, which requires driving traffic to it; The best experience assumes a well-documented OpenAPI spec to generate flows from
