Developer Infrastructure
Für Entwickler
Fast, DSGVO-compliant package infrastructure for Germany. Caching mirrors for npm, PyPI, Maven, and Go modules — deployed within minutes, billed per team.
Why teams switch to CodeSync
When your CI pipeline pulls from upstream registries across the Atlantic, every second adds up. CodeSync mirrors sit in Frankfurt and Nuremberg, so your builds resolve dependencies locally — consistently.
Up to 7× faster dependency resolution
Our Frankfurt edge cache serves 94 % of first-party and top-10,000 third-party packages without hitting upstream. A typical Node.js monorepo that takes 4 m 12 s on bare npm drops to 38 s after switching the registry URL.
Deterministic builds, zero drift
CodeSync snapshots the registry state at configurable intervals (default: every 15 minutes). Pin your CI to a snapshot tag like cs-npm-2024-06-14T08:00Z and reproduce any build exactly, months later.
Dependency conflicts caught before merge
The inline conflict scanner runs on every pull request and flags version skew across lock files. When lodash@4.17.20 and lodash@4.17.21 coexist in a workspace, the PR comment explains the impact and suggests a resolution.
DSGVO-compliant by design
All metadata, download logs, and team configuration stay within EU data centres. No telemetry leaves Germany, no US Cloud Act exposure. We publish our processor agreement and data map at codesync.dev/legal.
One config line per registry
Add registry = "https://de.codesync.dev/npm" to your .npmrc, drop a pip.conf snippet, or set GONOSUMDB for Go. No agents, no sidecars, no changes to your CI scripts.
Private registries, mirrored automatically
Point CodeSync at your Artifactory, Nexus, or GitHub Packages endpoint. We pull, cache, and serve your scoped packages alongside public ones — so internal teams get the same speed boost without extra infrastructure.
What developers say
Teams at mid-size SaaS companies, public-sector agencies, and research labs use CodeSync daily. Here's what they report after the first sprint.
Lena Weber, DevOps Lead at Meridio Health
"Our nightly pipeline for 14 microservices went from 22 minutes to 7 minutes after switching to CodeSync's npm and PyPI mirrors. The conflict scanner caught a duplicated axios version that had been causing intermittent flaky tests for months."
Tomáš Kříž, Senior Engineer at Railbook
"We evaluated Artifactory and Nexus first, but the setup complexity scared us. CodeSync was live in under an hour — we just updated three config files and pointed CI at the mirror. Our build cost dropped by roughly €300 a month."
Dr. Janine Schulz, Research Software Engineer at TU Darmstadt
"Data residency was non-negotiable for our grant-funded projects. CodeSync's Frankfurt-hosted mirrors let us pull PyPI and Conda packages without routing through US servers. The snapshot feature also means our computational notebooks stay reproducible years down the line."
