Break silos
One specification, every team
Qitab leverages the specification-as-code approach to bring software development velocity to systems engineering, eliminate tool bloat and brittle connectors.
The issues
Versioning pain
Avoid version mismatch, rollback issues and painful diffs. Whether it is configuration management, baselining or just collaborative work, trace, review and release changes via git.
Vendor lock-in
Qitab works with plain-text files in an open-source, human-readable language. No complex deployment, no vendor lock-in, no unreliable connector. You own the source of truth.
Formalization cliff
No need to duplicate requirements between each domain specific tool. Start in plain prose and progressively add typed, machine-checked constraints. Get the right level of formalism as the specification matures.
The cost of bad specifications
The numbers
2/3
Of projects delivered with defects because of incomplete specifications, in a third of those, the project is abandoned. Qitab helps connect all data sources to produce complete specifications.

Of engineering time wasted in doing low-value corrections, tool plumbing and information gathering. Qitab makes browsing and editing specification fast and easy.

More expensive to detect and fix a defect after deployment than during specification and design. Qitab detects defects as early as possible.

A single workflow
From tender to audit
Whether you're writing a tender response, running a compliance audit or formalizing a system architecture, collaborate without giving up on your domain-specific needs.
What Qitab does
Requirement management
Requirements explicitly contain your definitions: cross-reference, search and filter are easy and you don't lose time searching for a specific term or hidden-relation between requirements.
Model based engineering
Introduce the right level of modeling incrementally and make it understandable by everyone. Avoid over-engineering your models and keep them legible for every team.
Simulation and verification
Generate test scripts and monitors from requirements and match your actual verification and validation needs. Avoid meaning loss and distortion across the toolchain.
When to use it
Tendering
Directly import and breakdown your tenders and respond with accurate traceability and unambiguous requirements.
Compliance
Detect requirements flaws and defects before launching verification campaigns and minimize non-compliance risks at the earliest.
Engineering
From systems to domain-specific engineering, benefit from a holistic understanding of the design, and interconnect disciplines.
We adapt to your case
Onboarding, migration and compliance templates. Every engagement is scoped to your processes and regulatory context.

About Qitab
Qitab was built by a systems engineer who envisioned large engineering programs and couldn't find a tool that worked.
Its founder, Sami Dahoux, started his career at Alstom where he experienced first-hand the cost of fragmented specifications, vendor lock-in, and the gap between requirements documents and the systems they were meant to describe.
In 2021, he designed the req language, bringing the plain-text, git-native workflow of modern software engineering to systems specifications. Qitab is the editor built on top of it.
Qitab is an independent company. No investor pressure, no roadmap driven by someone else's priorities.
