Ecosystem 4hosting · Ireland

19 tools, one EUR invoice,
zero middlemen.

Every tool we host is tested with real Irish traffic: US SaaS scale-ups using a Dublin entity as EU data controller, fintech and regtech serving EU enterprise, Dublin and Cork digital agencies with multi-client setups. Servers in EU datacentres (Frankfurt/Amsterdam) — not physically in Ireland, with routing calibrated for Irish traffic via a London POP.

US SaaS with Dublin EU HQ — GDPR stack

Stack for US-incorporated SaaS using an Irish entity as EU data controller — the Stripe / HubSpot / LinkedIn pattern. Each tool here addresses a concrete Article 28 / Article 30 / SCC obligation, not a marketing checkbox.

PostgreSQL 16 + RLS

DB

Multi-tenant DB with row-level security

Row-level security for tenant isolation, streaming replicas, WAL archiving, PITR — the building block for an Article 32 'appropriate technical measures' argument under GDPR.

Keycloak

Auth

SSO + MFA + audit

Self-hosted identity with SAML/OIDC/WebAuthn. SCIM provisioning for enterprise tenants, full audit log of authentication events retained for the contract term.

Vault (HashiCorp OSS)

Secrets

Secrets + KMS

Self-hosted secrets management with transit encryption, dynamic database credentials, audit device logging every access — supports Article 32 encryption-at-rest and key-management obligations.

OpenTelemetry collector

Telemetry

Vendor-neutral telemetry

Standardised traces / metrics / logs pipeline. Lets you swap observability backends without re-instrumenting code — useful when finance asks to drop a SaaS vendor at Series B.

Audit-log service (self-hosted)

Audit

Immutable event ledger

Append-only audit log of every privileged action in the tenant — required for SOC 2, useful evidence for a DPA Article 28(3)(h) audit request from an enterprise EU customer.

Backups + PITR

Backup

Hourly + daily + weekly

Hourly snapshots with 24h retention, daily with 14d, weekly with 8 weeks. PITR for PostgreSQL via WAL archives — supports Article 32(1)(c) restore-availability obligations.

SaaS scale-up stack

What Series A-to-C SaaS teams running from Dublin or with a Dublin EU HQ actually deploy. Cost-conscious choices that scale to Series C without locking you into a single vendor.

Stripe-compatible billing

Billing

Subscription + invoicing

Stripe SDKs work without modification — we are not Stripe partners, the libraries just deploy. Webhooks with low Frankfurt latency.

Sentry (self-hosted)

Monitoring

Error tracking

Self-hosted on VPS for cost reduction vs SaaS Sentry at scale. Compatible with every official Sentry SDK.

Temporal (self-hosted)

Workflows

Durable workflows

Self-hosted workflow engine for long-running async jobs — alternative to Step Functions / SQS for EU-resident workloads.

Redis 7 + Sentinel

Cache

Cache + queues

Cache, session store, BullMQ / Sidekiq queues. Sentinel for HA, AOF persistence for queue durability.

Resend / Postmark compatible SMTP

Email

Transactional email relay

Outbound transactional email via authenticated SMTP relay. SPF/DKIM/DMARC configured per domain, bounce handling.

Self-hosted observability

Grafana/Loki/Tempo stack as a cost-conscious alternative to Datadog for Irish scale-ups — typical Series B saving is around 4-6k EUR/month.

Grafana

UI

Dashboards

Data sources: PostgreSQL, ClickHouse, Loki, Tempo, Prometheus. SSO via Google Workspace or Keycloak.

Prometheus

Metrics

Metrics

Self-hosted metrics collection. Service discovery via Consul or static targets, long-term storage via Thanos if needed.

Loki

Logs

Log aggregation

Grafana Loki stack. Index-free log aggregation — cheaper storage than Elasticsearch, sufficient for most SaaS workloads.

Tempo

Tracing

Distributed tracing

Grafana Tempo for distributed traces. OpenTelemetry-compatible ingestion, trace-to-logs correlation in Grafana UI.

Developer stack

What Irish developer teams actually use: Node + TypeScript for SaaS, Go for performance APIs, Python for data, plenty of Ruby on Rails legacy from the Dublin tech-scene boom.

Node.js 22 LTS

Runtime

JS runtime

Standard for Irish SaaS scale-ups. PM2 or systemd, Next.js SSR, end-to-end TypeScript via tRPC.

Go

Runtime

Go runtime

Static build, systemd deploy. For low-latency microservices and CLI tooling.

Python 3.12

Runtime

Python

Gunicorn / uWSGI for Django and FastAPI. Celery + Redis for async tasks, common in regtech / KYC workloads.

Ruby 3.3 + Rails 7

Runtime

Rails legacy

Still very present in Dublin SaaS — Intercom, Workvivo, Teamwork lineage. Puma + systemd, Sidekiq + Redis for background jobs.
