01 / The Tool

Complete files,
not snippets.

Most AI coding tools autocomplete inside an IDE. Coder AI generates entire deployable files — full HTML pages, complete REST APIs, whole test suites — in a single response. No IDE plugin needed. Browser-based, works in any environment, with output limits up to 64K tokens on the Power plan.

  • Complete file generation. Entire React components, full Python scripts, complete Django apps — not fragments.
  • Intelligent debugging. Paste a buggy function, get a precise diagnosis with a corrected version. Handles syntax, logic, security, and concurrency bugs.
  • Performance optimisation. Spot bottlenecks, get a clear explanation of why something is slow, and a faster version that explains the trade-off.
  • Security review. SQL injection, XSS, hardcoded secrets, insecure dependencies — flagged and fixed before they reach production.
  • Test generation. Auto-generate unit tests, integration tests, and edge cases. Coverage from 40% to 90%+ in minutes.
  • Refactoring & documentation. Modernise legacy code, generate docstrings, JSDoc, README files, and inline comments — explained as it goes.

02 / The Languages

Fifty-plus languages,
all expert-level.

Not a generalist that pretends to know everything. Expert-level assistance across the languages and frameworks developers actually ship in — from web stacks to systems programming to data engineering — without the quality drop-off you get on niche or low-level work.

  • Web & full-stack. JavaScript, TypeScript, Python (Django/Flask/FastAPI), PHP (Laravel/Symfony), Ruby (Rails), Go, full Next.js applications.
  • Systems & performance. Rust ownership and lifetimes explained clearly, C/C++ for embedded and game engines, ARM Cortex firmware, performance-critical algorithms.
  • Mobile & native. Swift/SwiftUI for iOS, Kotlin/Jetpack Compose for Android, React Native, cross-platform patterns.
  • Backend & enterprise. Java with Spring Boot, C# .NET / ASP.NET Core, Entity Framework, Blazor, Unity.
  • Data & databases. SQL query optimisation across PostgreSQL/MySQL/MSSQL, complex joins, indexing strategies, stored procedures.
  • DevOps & cloud. AWS Lambda & CDK, Kubernetes manifests, Helm charts, Terraform, Docker tooling, CI/CD pipelines.

04 / The Edge

Why Coder AI,
not the others.

Versus Copilot, Cursor, Tabnine — the differences are practical, not marketing. Complete files instead of snippets. Claude under the hood instead of generic LLMs. UK pricing instead of dollar exchange rates. A genuine day pass instead of a fourteen-day trial that asks for your card. Browser-first instead of IDE-locked.

  • Powered by Claude. Anthropic's Claude 4.5 Sonnet, Opus, and 3.5 Haiku — chosen because the code actually compiles. No hallucinated APIs, no invented function signatures.
  • Complete files vs snippets. Copilot autocompletes inside your IDE. Coder AI gives you the whole file ready to ship.
  • Browser-based, IDE-agnostic. Works in VS Code, JetBrains, Vim, Neovim — or no editor at all. No plugin, no installation, no editor lock-in.
  • UK pricing in GBP. Unlike US-priced competitors, no exchange-rate uncertainty, no foreign transaction fees on the card.
  • Real risk-free trial. £1.99 day pass means try it before you subscribe — not a card-required free trial that auto-bills.
  • Built by developers, for developers. The studio behind it ships software in production daily — every feature is one we wanted ourselves.
