Four sharp lenses that miss nothing.
Do your tests also feed back into CI/CD? We measure coverage, repeatability and reliability—so manual testing is no longer a bottleneck.
External APIs, legacy modules or third-party packages? We check dependencies for version control, licences and security risks.
Does the chosen framework still fit the roadmap? Our audit clarifies where modernisation is needed—and where it is not.
Cross-site request forgery, SQL injection, unencrypted data: we hunt for well-known and lesser-known weaknesses and provide clear remediation advice.
We often see teams waiting until after an incident to plan an audit. A pity, because preventive checks save on average 30–40 % refactor time later. It is not only about finding faults; an audit also shows what is already working well so you can build on it.
Lower risk of production stoppages
Faster onboarding of new developers
Transparency towards investors
Sharper security compliance
Higher development speed thanks to a clearer structure
A structured approach for rapid and thorough insight into the health of your codebase.
We listen to your goals, roadmap and the issues already gnawing at you. Context determines which parts of the code go under the magnifying glass first.
Using static analysis, linting and custom scripts we surface error patterns, duplication and code smells. We review some sections manually, especially when business-critical logic is unclear.
After the tools comes the human factor. Our seniors read the critical modules line by line, test design patterns and challenge naming conventions.
No waffle, just clear sections: architecture, database model, background processes, security, infrastructure, repository hygiene and UX consistency. Each finding receives an impact score, priority and suggestion for improvement.
We walk through everything live with your team. Questions, nuance or debate? We tackle them immediately so the report matches day-to-day reality.
A codebase is an ecosystem. When one dependency becomes outdated, the rest will eventually be affected. That is why we start with the pillars:
DDD, MVC, hexagonal—each pattern has value, provided it is applied consistently. We check whether modules are small enough, whether layers secretly cross each other and whether the chosen framework (Laravel, Spring, Next.js) is still scalable for the roadmap.
In practice we often see columns that accept NULL without reason, missing indexes and relationships enforced in the wrong place. That costs performance and can break integrity. A single missing foreign-key can even cause data loss after an innocent deploy.
Cron jobs, queue workers, event streams—does everything run in the right order and with sufficient monitoring? We simulate peak load and measure throughput to surface bottlenecks.
Think of it as a digital workshop. Unnecessary branches, gigantic commits and missing pull-request templates make maintenance hard. We check branch strategy, commit descriptions and automate linting checks in the CI pipeline.
Jira, GitHub Projects or Azure Boards? We do not mind—as long as tickets are clearly linked to commits. Only then can you understand afterwards why something was built the way it is.
Code without documentation is fine—provided the code is crystal clear. That is often where it pinches. We assess READMEs, ADRs and in-code comments for accuracy and tone.
Security testing is shifting towards development, so we integrate SAST scans into every build. Your team sees vulnerabilities right at the pull request, not in production.
Tools such as GitHub Copilot generate code at lightning speed. Handy, but they sometimes include snippets with unclear licences. An audit checks origin and compatibility—before you run legal risks.
Microservices, serverless and containers require different audit frameworks: think distributed tracing and resource limits. We align our checklist accordingly so you remain future-proof.

Yield.inc is a new asset manager in the Netherlands that focuses on excellent customer experience, sustainability and technology. When faced with the question of whether to develop our platform in-house or with a partner, we got in touch with Spartner. We are still 100% behind the choice for Spartner because we own the source code and with Spartner, a deal really is a deal, whether it concerns the delivery date or the agreed budget!

Spartner is involved and contributes in our search for innovations and always delivers top-notch work. After the first Huurda.nl version got out-dated, we collaboratively launched a completely new version in 2020.

Innovation and change are not always welcomed with equal enthusiasm by our employees, man is a creature of habit but as a company you have to dare to move forward and the need for a contemporary drawing program for the realization of various constructions with our Masterbloc bricks was high. For us but also for Spartner, this challenge was a bit of pioneering and together we had to overcome some hurdles to arrive at a beautiful and efficient business tool. A development and learning process for both parties, in which the feedback of questions and desired adjustments by our employees to Spartner was always in good consultation and we could count on quick feedback and targeted solutions. We continue to exchange experiences with Spartner and look back and forward to a successful collaboration.

As jurists with knowledge of IT, we highly value quality; within code, but also in process. The high work-level and trustworthiness of Spartner gives us the capacity to continuously create innovative features.

A review focuses on a single feature and usually happens under time pressure. An audit covers the entire codebase, examines patterns, processes and security. It is broader and deeper.
Usually we just provide repository access and a brief kick-off. After that Spartner does the heavy lifting. You only need time again during the feedback session.
Certainly. Some clients only want security, others only performance. We do advise including at least architecture and database.
No panic—we will not burn anything down. You receive a priority list with concrete steps, so you can improve in a structured way without stress.
Absolutely. UX inconsistencies can indicate underlying code-structure issues. We link visual glitches to technical causes.
We guarantee an honest, well-founded opinion. The actual fix depends on implementation, but we remain available for advice.
No, everything stays confidential. Only you decide what may be shared.
Absolutely. We can jump in directly or coach your team, depending on what you need.
