## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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

Startups.RIP is a research library of 2,200+ startup stories — including many Y Combinator companies — that documents what each one built, how it ended, and how you could rebuild it today. Free accounts browse research reports and build plans; Pro adds implementation-ready technical specs and a CLI that imports the research into coding agents like Claude and Codex.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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
