Ketryx Alternative: Tandem vs Ketryx for Hardware Programs

Software teams using Ketryx generally don't panic when an audit notification arrives. Their git commits, pull requests, and Jira issues link directly to IEC 62304 work items, generating clean software traceability matrices with minimal manual overhead.

Then the auditor asks about the enclosure revision, the motor mount bracket, or the updated thermal housing.

At that point, the process falls apart. Mechanical engineers end up digging through SolidWorks folder structures, searching Slack threads from eight months ago, and manually copy-pasting CAD screenshots into Word documents to prove why a dimension changed. Ketryx solves software compliance for regulated medical devices, but physical hardware is an entirely different domain. If your program builds physical machinery, software traceability covers only half the product.

What Ketryx Actually Does (and What It's Designed For)

Ketryx entered the medical device market with a clear focus: treating regulatory compliance as code. Founded to bridge modern software development practices with FDA quality system regulations and IEC 62304 standards, Ketryx is an overlay layer across software development environments.

Instead of forcing software engineers into legacy requirements databases, Ketryx integrates directly with Jira, GitHub, GitLab, and Azure DevOps. It pulls data from developer commits, branch merges, and pull request reviews, mapping those actions against risk management files (ISO 14971) and verification test results. The software automatically maintains the software Design History File (DHF) and generates Software Bills of Materials (SBOMs).

For Software in a Medical Device (SaMD) or teams where the product is 95 percent code running on commodity compute boards, this architecture works well. Developers stay in their preferred development environments, while quality leads get automated compliance artifacts without chasing engineers for manual signatures.

The system works because software development artifacts are digital, text-based, and tracked through version control repositories that expose predictable APIs. Git commits provide a clean audit log of who changed what code, when, and under which pull request.

Where Ketryx Stops: The Mechanical CAD Blind Spot

The problem emerges when you build physical machines. A surgical robot, an automated drug delivery pump, or an in-vitro diagnostic instrument is not just code. It is a complex assembly of machined parts, injection-molded housings, fluid manifolds, and structural frames.

Ketryx is not designed around mechanical CAD workflows. It does not monitor CAD assemblies, part revisions, or the engineering review comments that drive physical geometry changes.

This creates a severe visibility gap in regulated programs. When a mechanical engineer alters an internal wall thickness in CAD to solve a thermal constraint, that decision happens entirely outside Ketryx. The system requirement lives in a document, the software team updates an alarm threshold in Jira, but the CAD model evolves in an isolated PDM repository.

When teams try to reconcile these domains for an audit, they discover their automated traceability stops at the software boundary. Building a unified traceability matrix for medical device design becomes a manual exercise. Quality teams must manually cross-reference CAD revision histories, PDF drawings, and email approvals against physical test reports. Ketryx cannot help here because it has no model of mechanical hardware context.

What Tandem Covers That Ketryx Doesn't

Tandem was built specifically to solve this physical engineering gap. Headquartered in San Francisco, Tandem is an AI-native hardware development platform that connects design intent, requirements, CAD changes, and validation evidence in a single system.

While Ketryx sits over code repositories, Tandem sits over the engineering tools where physical products take shape. Tandem offers off-the-shelf integrations with SolidWorks, Onshape, Fusion, and NX, alongside Excel, Google Sheets, and Slack. For larger enterprise environments, Tandem connects to Teamcenter and 3DExperience via custom deployed-work integrations.

Tandem links system requirements and constraints directly to CAD changes and physical validation data. When an engineer modifies a part geometry, Tandem preserves the design rationale behind that change. If a requirement states that a diagnostic unit must survive a one-meter drop test, Tandem maintains the thread connecting that requirement to the specific CAD structural ribs, the design review discussions, and the physical drop-test reports.

Tandem is not an authoring CAD tool, and it is not a PDM or PLM replacement. It does not store raw geometry files or draft engineering drawings. Instead, Tandem is the context layer above CAD and PDM, tracking the hardware development loop from early definition through review, validation, and release documentation.

For teams managing physical hardware programs, Tandem captures the design decisions that otherwise remain trapped in engineering heads or lost across CAD revisions.

Other Alternatives Worth Considering (Jama Connect, Polarion, Matrix Req)

If you are evaluating options to replace or complement Ketryx across your engineering organization, several platforms approach the traceability problem from different angles. Here is how the top alternatives compare.

1. Tandem Best for: Hardware engineering teams that must link mechanical CAD changes, design intent, and validation evidence to requirements. Honest limitation: Tandem focuses on hardware engineering and does not monitor git commit logs or provide automated IEC 62304 static code analysis.

2. Matrix Requirements (MatrixALM / MatrixQMS) Best for: Medical device companies seeking a flexible, web-native quality and requirements overlay that links directly to Jira without the overhead of heavy enterprise platforms. Learn more in our guide on Matrix Requirements alternative options. Honest limitation: Matrix Requirements is designed primarily around text specifications, software items, and risk tables. It lacks direct, bidirectional CAD context for mechanical teams.

3. Jama Connect Best for: Enterprise systems engineering organizations requiring formal Model-Based Systems Engineering (MBSE) workflows and complex requirement allocation across thousands of sub-systems. Honest limitation: High implementation complexity, steep administrative overhead, and significant licensing costs make it cumbersome for fast-moving hardware startups.

4. Siemens Polarion ALM Best for: Large manufacturing organizations already invested in the Siemens product ecosystem that want a single ALM environment for application lifecycle governance. Honest limitation: The interface and configuration requirements reflect legacy enterprise software paradigms, often creating friction for engineers working in agile sprints.

Ketryx vs Tandem: Side-by-Side Comparison

The difference between Ketryx and Tandem comes down to the engineering disciplines they support. Both platforms are context overlays rather than authoring repositories, but they operate on opposite sides of a hardware program.

Primary Focus: Ketryx governs software and firmware development compliance, specifically targeting IEC 62304, ISO 14971, and FDA software documentation. Tandem governs hardware development, tracking design intent, requirements, CAD changes, and physical validation evidence across the entire hardware lifecycle.

Core Data Sources: Ketryx connects to GitHub, GitLab, Jira, and Azure DevOps, alongside Bitbucket. Tandem connects to SolidWorks, Onshape, Fusion, and NX, as well as spreadsheets and Slack.

Traceability Outputs: Ketryx produces software DHFs, code verification matrices, cyber bills of materials, and automated commit-to-requirement links. Tandem produces end-to-end hardware traceability connecting customer requirements, technical design rationale, CAD model revisions, review history, and physical validation test results.

Underlying Philosophy: Ketryx treats regulatory documentation as a byproduct of writing code. Tandem treats hardware traceability as a byproduct of mechanical design reviews and CAD changes, without forcing engineers to fill out disconnected spreadsheets during an engineering change order process.

Neither tool replaces the engineer's primary workspace. Ketryx does not write your firmware, and Tandem does not edit your 3D parts. Both extract decision context to protect the integrity of the program.

How to Choose Based on Your Program's Actual Gap

Choosing the right platform depends on where your product risk and engineering friction actually exist.

Audit your past three engineering delays. If your regulatory findings stem from missing software code reviews, unlinked Jira tickets, or inadequate cybersecurity documentation for an off-the-shelf micro-controller, Ketryx is the tool built for that problem. It solves the software traceability headache cleanly.

If your delays stem from hardware rework, the choice changes. When prototype assemblies do not fit together because a CAD constraint was altered without communicating the change, Ketryx cannot help you. When an auditor asks why a structural enclosure thickness changed between proto and production builds, and your team spends two weeks excavating old CAD versions and Slack channels to justify the decision, your gap is in hardware context.

In that scenario, a software-only ALM leaves your mechanical engineering team completely disconnected from the quality system. You need a platform like Tandem that interfaces directly with CAD environments and captures the rationale behind physical revisions.

If your organization is building enterprise defense systems with strict V-model contractual flow-downs across three tiers of external prime contractors, look toward Jama Connect or Polarion. For agile hardware teams building complex electromechanical devices, heavy ALM tools often introduce more friction than clarity.

Can You Run Both? When Ketryx and Tandem Complement Each Other

For many regulated medical device, robotics, and aerospace companies, the real answer is not choosing between Ketryx and Tandem. Running both in parallel is the more effective approach.

Complex mechatronic products require both high-velocity firmware development and rigorous mechanical validation. Forcing mechanical engineers into Jira and GitHub to document physical tolerances feels unnatural and yields poor compliance records. Similarly, forcing embedded software developers into CAD-centric engineering workspaces creates friction and slows release velocity.

By pairing Ketryx with Tandem, regulated organizations get specialized context layers for each domain:

Ketryx manages the digital domain: git commits, pull requests, automated unit testing, IEC 62304 verification, and software release artifacts.

Tandem manages the physical domain: system requirements, mechanical design rationale, SolidWorks and NX revisions, physical test evidence, and release documentation.

Both platforms cut manual audit prep by pulling context directly from the tools engineers already use. Instead of relying on a monolithic legacy PLM system that fails to satisfy either software or mechanical workflows, progressive hardware teams pair best-in-class overlay layers to achieve complete product traceability.

Conclusion

Relying on software compliance tools to track mechanical engineering decisions creates dangerous gaps in any regulated hardware program. Ketryx provides automated traceability for code, but it leaves mechanical CAD changes and physical design rationale invisible to auditors.

Tandem closes this gap by connecting requirements, CAD revisions in SolidWorks, Onshape, Fusion, and NX, and validation evidence in one shared context layer.
