## 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.

**Tarifs et offres:** 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.

**Forces:** 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

**Limites:** 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

## Vellum

Vellum is a personal AI assistant that you own and customize. It runs locally on your machine or in Vellum Cloud, remembers your context over time, connects to your tools and takes real actions like email, calendar, research and file work, with model choice across OpenAI, Anthropic, Gemini or local open weights via Ollama.

**Tarifs et offres:** Free to download and run locally. Vellum Cloud subscriptions start at $30/month (Mighty), $100/month (Super) and $200/month (Ultra), each with dedicated compute, storage and bundled credits. Credits are consumed by actions. The site also notes the Personal Assistant Platform is shutting down by December 13, 2026, with instructions to download your assistant.

- **Long-term personal memory:** A custom-built memory system that retains you, your people, preferences and work across every conversation, rather than resetting each session.
- **Skills and tool integrations:** Connect Google Workspace, Slack, Notion, your filesystem and community plugins so the assistant can send emails, manage calendars, browse, create slides and run research.
- **Fine-grained permissions:** Set permissions so sensitive actions like emailing new contacts or modifying key files require approval until you mark them trusted.
- **Model choice:** Switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama at any time, keeping you free of a single vendor lock-in.
- **Local-first privacy:** Your assistant runs locally by default with open-source code you can inspect; Vellum Cloud offers an isolated container provisioned just for you.
- **Available everywhere:** Native on Mac and available on iOS, Android, web, voice, email, Telegram, Slack and terminal, all sharing the same identity, memory and schedules.

**Forces:** Runs locally by default with open-source code you can audit; Genuine long-term memory that persists across every conversation; Model-agnostic: OpenAI, Anthropic, Gemini or local open weights via Ollama; Takes real actions across email, calendar, files and connected tools

**Limites:** The homepage banner states the Personal Assistant Platform is shutting down by December 13, 2026; Proprietary cloud tiers at $30–$200 per month, and credit-based actions can add cost; High-stakes actions require approval prompts until you mark them trusted, adding friction early on; Mac-first native experience, so non-Apple users depend on web and chat surfaces
