The BOE never sleeps. Now neither does the watch.

Every gestoría in Spain has the same quiet dread: a convenio colectivo update lands in the BOE, the salary tables change, and a client’s payroll is quietly wrong until someone notices. ConvenioAlert reads the BOE every day, spots new agreements, salary-table revisions and actas, classifies them by sector, parses the salary figures — and tells exactly the right subscribers.

It is a focused B2B product at €19 a month: one job, done with the reliability of infrastructure rather than the enthusiasm of a newsletter.

What we designed & built

From boletín to inbox, classified.

The value is precision: the right convenio, to the right adviser, with the numbers already extracted.

01

Daily BOE watch

Automated ingestion of every relevant publication — including parsing the notorious "tabla_girada" rotated salary tables that defeat casual scrapers.

02

Deterministic classification

A CNAE and keyword taxonomy classifies agreements by sector with zero LLM in the hot path — the same input always produces the same routing.

03

Alerts advisers trust

Double opt-in via Resend, sessionless magic-link access, and a subscription flow on Stripe Payment Links.

ConvenioAlert — sector chips and the latest collective agreements rendered as cards
The sector map we designed — fresh convenios from the BOE land as cards the day they are published.
The tech

Under the hood.

A monitoring product is only as good as its own monitoring.

01

Watching the watcher

Source-health monitoring raises dark-source alerts if the BOE feed pattern changes — the system knows when it has gone blind, which is the failure mode that kills scraping products.

02

Free-tier discipline

CPU and subrequest budgets are engineered to run the whole daily pipeline within Cloudflare’s free-tier limits — zero runtime dependencies, template-literal SSR, nothing wasted.

03

Hardened edges

WebCrypto HMAC verification on Stripe webhooks, per-IP rate limiting plus Turnstile on public forms, RGPD compliance, programmatic SEO for discovery, and 15 test files across the pipeline.

On the work · Viva Grafix, 2026

ConvenioAlert turns a legal-publication firehose into a precise, affordable alarm for the people whose job depends on it — built lean enough to run on pocket change, and paranoid enough to notice when its own sources go dark.
