Athlete management, testing, programming, reporting, and scheduling — unified. No paywalls. No fragmented workflow. No software built by people who've never stood on a gym floor.

Athletes Supported
Five tools. Zero connection.
Testing in a spreadsheet. Programming in another app. Athlete notes in email. Nothing talks to anything else — and every handoff loses context.
Paywalls on your own data.
Reports locked behind tiers. Exports restricted. Per-seat pricing that punishes growth. Built for subscriptions, not for coaches.
More software. Less coaching.
Every new athlete adds admin. Every new tool adds friction. The systems don't save time — they cost it.
Onyx Performance OS connects every surface — athlete records, testing data, training programs, schedules, and performance intelligence — into a single coherent system.
When everything is connected, the work changes. Less admin. More signal. More time coaching.
Athlete Management
Full profiles, onboarding pipeline, health monitoring, and longitudinal history — all connected and instantly accessible.
Performance Testing
Structured testing workflows for every assessment domain. Results feed directly into athlete profiles and intelligence surfaces.
Programming
Training programs, session templates, week structure, phase management, and load progression — built for how coaches actually plan.
Scheduling
Appointments, group classes, and session planning across your facility — unified with athlete records and programming.
Reporting
Session summaries, longitudinal trends, and athlete reports. Your data, your reports. No export restrictions. No locked tiers.
Performance Intelligence
Priority signals, readiness flags, and metric observations derived from testing data — surfaced at the moment they matter.
Structured testing workflows for every assessment domain. Results connect directly to athlete profiles, programming decisions, and intelligence signals. The data works for you — you don't work for the data.
Collect results for any testing domain — force plate, sprint, body comp, strength
Organize athlete data with structured QC review and approval workflows
Connect results to individual athlete profiles and longitudinal history
Generate session reports and trend analysis automatically
Track progress over time and surface meaningful changes
Feed testing data into programming decisions and priority signals

Strength Coaches
Testing, programming, and monitoring in one place. Less setup, more coaching.
Sports Scientists
Structured workflows, metric observations, and intelligence signals grounded in your testing data.
Performance Directors
Full roster visibility. Priority signals and trends — without building custom dashboards.
Gym Owners
Athlete management, staff, scheduling, and reporting in one system. Built for the business side too.
Private Facilities
Professional-grade tools. No enterprise pricing. The same system boutique facilities and elite teams need.
Onyx Performance OS was built by a strength coach, sports scientist, and gym owner who ran out of patience with fragmented systems, paywalls, and software clearly designed by people who've never stood on a gym floor.
The tools existed. They just didn't connect. Athlete data lived in a spreadsheet. Programming lived in a different app. Testing results went somewhere else entirely. Every week was more admin work than it should have been.
This is the system we always wanted to use. So we built it.
01
Build Your Roster
Add athletes, set up profiles, and onboard through a structured intake flow. Your full operation in one place.
02
Run Assessments
Log testing data across any domain. Results go through QC review before connecting to athlete profiles and downstream surfaces.
03
Build & Assign Programs
Create training programs, assign to individuals or groups, and track load and progress across phases.
04
Track & Iterate
Monitor development, surface priority flags, generate reports, and plan the next training block — all without switching tools.
