The site is split into focused sections, each doing one thing well:
- AI research assistant — agentic bot that searches academic catalogs, reads the most relevant papers, and writes a cited answer.
- Paper-to-code finder — agent that searches GitHub for implementations of any academic paper and ranks them by quality.
- Codebase orientation — agent that reads a GitHub repo's README and key source files, then writes a written orientation.
- Cron explainer — paste a cron expression, get plain-English meaning, next trigger times, and common gotchas.
- JSON formatter & validator — pretty-print, minify, sort keys, or convert JSON to YAML or XML; errors pinpointed by line and column.
- JWT decoder & verifier — decode header and payload, see expiration timing, and verify signatures with HS256/384/512 or RS256/384/512 keys.
- WCAG contrast checker — AA/AAA scoring with a real text preview at three sizes and a one-click "suggest a passing variation".
- UUID + ULID generator — UUID v4, v7, and ULIDs in bulk, with timestamp decoding for v7 and ULID.
- Jobs — curated tech roles from companies like Stripe, Anthropic and Cloudflare, refreshed twice daily.
- Tools directory — a catalogue of developer tools across IDEs, AI coding assistants, CI/CD, databases, monitoring and more.
- Career toolkit — free job-application tools: ATS resume checker, AI cover letter generator, interview question bank, salary negotiation scripts.
- News — daily aggregated posts from top engineering blogs and Hacker News.
- Blog — long-form writing on tech hiring, AI/ML careers and engineering career paths.
- Layoffs tracker — verified tech layoffs since 2022, every entry primary-sourced.
Roles are filtered to tech disciplines only: Backend, DevOps, AI/ML, Security, Frontend, Data, Mobile, QA, Product, Design, DevRel and Quant. Pair the listings with the career toolkit to sharpen your application before you apply.
The Code Deck indexes roles from company career pages automatically. If your company uses Greenhouse or one of our supported sources, your open tech roles are likely already listed for free.
Want roles to stand out? Featured listings sit above organic results on relevant searches. Self-service from £49.

Featured placement
Pin your roles to the top of relevant searches. 7-day boost (£49) or 30-day premium (£149). Fixed price, no auction, live in minutes.
Roles are pulled directly from top tech employer career pages and refreshed twice a day. Every listing carries a real description from the source. When a role is filled or removed, it drops off within 24 hours.
The lab is a growing collection of small dev tools and AI experiments. AI experiments include a research assistant that searches academic catalogs (OpenAlex, Semantic Scholar, Crossref, arXiv) and writes a cited answer; a paper-to-code finder that locates and ranks GitHub implementations of any academic paper; a codebase orientation tool that reads a repo and writes a written tour; and a cron explainer. Pure browser utilities include a JSON formatter & validator, a JWT decoder & verifier, a WCAG contrast checker, and a UUID + ULID generator. All run client-side or self-hosted, with no third-party API calls in the loop.
More experiments will land here over time.
