ReqProof mathematically proves your requirements are consistent, complete, and realizable before you write a single line of code. Found a crash bug in Tyk API Gateway that 400 lines of code review missed.
For safety-critical engineering teams dissatisfied with manual requirements processes, these three pain points are unavoidable, urgent, and dangerously underserved.
Requirements live in Confluence. Code lives in Git. Tests live in CI. Nothing connects them. When code changes, nobody updates the spec. When the spec changes, nobody updates the tests. Drift is invisible until it causes an incident.
Most testing catches implementation bugs. But what about requirements that contradict each other? Or edge cases nobody specified? The costliest defects are the ones you never wrote a test for because the spec never asked the question.
DO-178C, ISO 26262, and IEC 62304 demand traceability matrices, MC/DC evidence, and SRS documents. Teams spend months assembling paperwork that is outdated the moment it is printed.
One command. Six verification layers. Each catches a different class of defect that no amount of testing can find.
Define requirements in YAML with FRETish temporal logic. Or write plain English and let AI translate with 86% accuracy.
Kind2 and Z3 solvers prove realizability, consistency, and data property correctness for all possible inputs. Not testing -- mathematical proof.
Gap analysis flags every unconstrained output. It forces the questions nobody thought to ask -- like the one that found the Tyk crash bug.
FLIP generates MC/DC test traces. Z3 produces boundary-value fixtures from solver models. Automatic, exhaustive, from formal proofs.
Comment-based annotations in 20+ languages. Automatic bidirectional traceability. Suspect link detection when things drift.
Generate NPR 7150-compliant SRS documents with traceability matrices, coverage heat maps, and verification evidence.
A complete formal verification toolkit that fits into your existing developer workflow.
Prove requirements are realizable, consistent, and complete using Kind2 and Z3 SMT solvers. Not testing -- mathematical proof that catches contradictions no test suite can find.
Every requirement links to code and tests via simple comments. // SYS-REQ-001 in any language. Automatic linking. Suspect link detection when things drift.
Write requirements in plain English. ReqProof translates to formal FRETish notation with 86% accuracy, validates instantly, and suggests fixes. No formal methods expertise required.
reqproof verify runs the entire pipeline in one command. reqproof ci for GitHub Actions and GitLab CI. Fits your existing developer workflow.
Comment-based traceability scanning in 20+ programming languages. Go, Python, Java, C, C++, Rust, TypeScript, and more. Works with any codebase.
Generate NPR 7150-compliant SRS documents with traceability matrices, coverage heat maps, and verification evidence. Maps to DO-178C Tables A-1 through A-10.
A real production system. 400 lines of Go. 2 hours of specification work. Here is what ReqProof found.
"The bug was found because gap analysis forced the question: 'what happens when the store is unavailable?' Nobody had asked until the spec required an answer. The code never checked for nil -- and it had been in production for years."
Built on NASA FRET formal methods heritage. Generates compliance artifacts for the standards that matter.
Section-by-section mapping for DO-178C Tables A-1 through A-10, ISO 26262 Part 6/8, IEC 62304, and 7 additional standards. SRS documents include coverage heat maps, traceability matrices, and verification evidence.
A fundamentally different approach. Not a cheaper copy -- a new category of tool that DOORS cannot replicate.
