## 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

## Luminance

Luminance grew out of research at the University of Cambridge and has been building contract-focused AI for over a decade. Its core proposition is that contracts contain knowledge about how a business actually operates, and that knowledge should be visible to every team that depends on it, not just to lawyers who happen to open the file.

The platform covers three broad jobs. Discovery turns a contract portfolio into actionable insight by surfacing risk, obligations and commercial opportunities without manual searching. Negotiation brings precedent, playbooks and accepted positions into the drafting process so teams review faster and hold on to the terms that matter. Automation keeps contracts moving through connected intake-to-signature workflows that pull stakeholders and systems into one process.

Luminance positions itself as an enterprise-grade offering rather than a self-serve tool, and it reports use across Legal, Procurement, Finance, Sales and Executive teams, with over a thousand enterprises claimed as customers. It is designed around the breadth of contract types a large organisation holds, and around the compliance and audit expectations that come with that scale.

**Pricing & Plans:** Contact for pricing. Luminance does not publish plan details or per-seat rates; it runs a demo-led enterprise sales process and quotes per organisation.

- **Portfolio-wide contract discovery:** Turns a contract portfolio into searchable insight, surfacing risk, obligations and commercial opportunities in seconds rather than through manual review.
- **Negotiation with precedent and playbooks:** Brings prior positions, accepted clauses and negotiation playbooks into each review so teams move faster and protect the terms that carry risk.
- **Workflow automation from intake to signature:** Connects stakeholders, systems and actions into a single workflow so contracts keep progressing instead of stalling between teams.
- **Cross-functional access:** Delivers contract context to Legal, Procurement, Finance, Sales and Executive users, including supplier terms, auto-renewals and unrecognised commitments.
- **Purpose-built legal AI architecture:** Combines specialist legal models with contractual context so documents are understood in context rather than as plain text.

**Strengths:** Deep specialisation in contract intelligence rather than general-purpose document AI; Enterprise scale: used by organisations reporting thousands of users per company; Serves five different functions from one contract knowledge base; Backed by more than a decade of legal AI research and development

**Limitations:** No self-serve or published pricing, so smaller teams cannot evaluate it on their own; Implementation and onboarding are enterprise-scale and not suited to one-off projects; Value depends heavily on having a large existing contract portfolio to analyse
