Visaproof
Visa-friendly developer jobs in Europe, with the evidence for every answer:
visaproof.azamatos.com. New roles that sponsor a visa, every morning on Telegram:
@visaproof, and in Russian @visaproof_ru.
Live since 2026-10-24, open to search engines since 2026-10-27. On 2026-10-27: about 15,000 open developer
roles in the EU, EEA, UK and Switzerland at 2,500 companies, found on 16,000 companies' own job boards.
A free job finder for software developers who need a visa to work in Europe. It reads open roles straight from
companies' own job boards and answers the questions a relocating developer asks first, with proof:
- Will they sponsor a visa? Will they help me relocate? Two separate answers, each with the exact sentence
from the posting ("we sponsor visas for the right candidate") and the employer's entry in an official sponsor
register where one exists.
- Can I actually get the permit? In the Netherlands only an IND recognised sponsor can hire a Highly Skilled
Migrant. In the UK the employer needs a sponsor licence. In Germany any employer can hire on an EU Blue Card if
the salary clears the threshold. The site checks what it can and says what it can't.
- Do I need the local language? "German required" is pulled out of the posting, so you can filter it away.
- Is it still open? Every role is re-checked against the company's board several times a day.
Every answer shows where it comes from: the quote, the register entry or the salary rule, with its source and the
date it was checked. "Unknown" is a valid answer; nothing is guessed from a company's size or reputation.
How it works
company job boards (Ashby, Greenhouse, Lever, SmartRecruiters, Common Crawl index
Personio, Recruitee, Workable, Workday) (finds new boards weekly)
│ │
▼ ▼
pipeline, every 6 hours (Node + TypeScript, Docker, systemd timers on a small server)
read board → engineering roles in Europe → new / changed / closed → facts from the text
│ ▲
▼ │ daily
Postgres ◀─────────── sponsor registers (Dutch IND, UK Home Office)

website (Nuxt): search, filters, job pages with the evidence, company and country pages, method, status
- A board is read in one request where its API allows it; a few boards need one more request per new role.
- Only software engineering roles in the EU, EEA, UK and Switzerland are kept.
- Employers are matched against the official registers.
- A language model (Claude Opus 5.5) reads each new or changed posting that mentions visas, permits or relocation
and returns the facts with quotes; a quote that isn't word for word in the posting is dropped. A second pass
(Claude Sonnet 5.5) checks every posting for the languages it requires. A labelled set of 200 postings measures
both, and the numbers are on the site's Method page.
- Each posting's technologies are recognised from a dictionary with aliases (Go = Golang, k8s = Kubernetes), so
search finds "C++" and ".NET" and never mixes up Java and JavaScript.
How accurate it is
Measured on a labelled set (apps/pipeline/eval): 200 postings drawn at random in four groups and labelled
separately from the extractor, by agents following one written guide. The model is only given postings that
mention visas, permits or relocation: 161 of the 200.
| Who reads the posting | "Sponsors a visa": precision / recall | "Won't sponsor": precision / recall |
|---|
| Keyword rules (the baseline) | 33% / 90% | 90% / 37% |
| Claude Opus 5.5 (in use), quotes verified | 100% / 100% | 98% / 96% |
The bar was 95% precision for "sponsors": a wrong "yes" costs a visa applicant the most. The sample is small (22
postings offer a visa), so a perfect score still means about 85% at the low end of a 95% interval. The language
check gets 200 of 200 postings right. Every quote is checked word for word against the posting, and none has had
to be dropped. The details, and what the first runs found: docs/findings.md.
Built with
- Pipeline: Node 22 and TypeScript (run directly, no build), Postgres 18, DuckDB over Common Crawl's index,
Claude Code in print mode for the language model, Docker and systemd timers on one small server, alerts on
Telegram.
- Site: Nuxt 4 (Vue 3, server-rendered), Tailwind CSS 4, own components on Reka UI, share images drawn with
Satori and resvg, behind Caddy and Cloudflare.
- Quality: TypeScript strict, ESLint (
strictTypeChecked), Prettier, Vitest, Playwright with axe on a phone
and a desktop in both themes, GitHub Actions. Lighthouse on a phone: performance 96–100, accessibility and SEO 100.
What it isn't
- Not legal advice. Visa rules change; the site links to official sources and shows when it last checked.
- Not a copy of the postings. It shows extracted facts and short quotes, then sends you to the original.
- Not a recruiter. No accounts, no CV uploads, no tracking beyond privacy-friendly page counts.
Run it
Needs Node 22.18+, pnpm 10 and a Postgres database (18 on the server).
pnpm install
export DATABASE_URL=postgres://user:pass@localhost:5432/visaproof
cd apps/pipeline
node src/cli.ts migrate
node src/cli.ts seed boards.json # [{ "ats": "greenhouse", "slug": "example" }, …]
node src/cli.ts ingest # read the boards
node src/cli.ts registers # load the IND and UK registers, match companies
node src/cli.ts technologies # recognise each posting's technologies
node src/cli.ts report # the numbers, as Markdown
cd ../web
NUXT_DATABASE_URL=$DATABASE_URL pnpm dev # the site on http://localhost:4003
Checks, as CI runs them: pnpm typecheck && pnpm lint && pnpm format:check && pnpm test, and the browser tests
(Playwright and axe, against a test database of made-up roles): pnpm --filter web e2e.
The server setup (Docker Compose, timers, deploy) is in deploy/README.md.
