## 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

## Startups.RIP

Most startup libraries focus on the winners and skip the rest. Startups.RIP takes the opposite view: it is an archive of 2,234+ company stories — many from Y Combinator — that records what each one built, why it stalled or succeeded, and what a founder could do differently today. Browsing is filtered by batch and category, and each entry shows a clear status label such as Acquired, Inactive or Active so you can see the outcome at a glance.

The deeper value sits in the build material. Free accounts get the full research reports plus build plans and prototypes, so the lesson becomes a project rather than a trivia. Pro unlocks implementation-ready technical specs, letting developers read how a product was actually assembled and rebuild a modern version without starting from a blank page.

A research chat lets members query the archive conversationally, while on-demand research covers companies you cannot find. The Pro Agent CLI then exports reports, rebuild plans and specs directly into coding agents like Claude and Codex, closing the loop from "what happened" to "here is code."

**Pricing & Plans:** Freemium. The Free tier includes all completed research reports, build plans and prototypes, and research chat for signed-in members. Pro costs $15/month (or $180 billed annually, a 25% saving) and adds implementation-ready technical specs, on-demand research and the Agent CLI. Renewal can be cancelled anytime.

- **2,000+ startup case files:** A searchable library of over 2,234 startup reports with status labels such as Acquired, Inactive and Active, organised by YC batch and industry.
- **Build plans and prototypes:** Each featured company comes with practical build plans and prototypes that turn the historical lesson into a concrete project you can start.
- **Implementation-ready tech specs:** Pro members unlock implementation-ready specifications that describe how to actually build the product, not just what the original team did.
- **Research chat:** Ask questions about any report or build plan and get answers drawn from the archive, rather than reading every page manually.
- **Agent CLI for coding agents:** The Pro CLI pulls reports, rebuild plans and specs straight into Claude, Codex and other coding agents so you can ship from the research.

**Strengths:** Turns startup post-mortems into concrete build plans and specs; Searchable archive of 2,234+ companies with clear outcome labels; Agent CLI feeds research straight into Claude, Codex and similar tools; Free tier covers reports, build plans and research chat

**Limitations:** Technical specs and the coding-agent CLI require a paid Pro plan; Coverage skews to YC companies, so non-YC failure history is thinner; Report depth varies by how much public information exists for each startup
