Why not DIY?
You could build this. You shouldn't have to.
Every serious team needs to know its systems survive failure. Almost no team should spend months building the machine that tests it.
Being good at GameDays doesn't sell your product.
Think about what your customers actually buy. Whatever it is the app, the platform, the widgets you lose sleep over they buy that. They don't buy your ability to run elegant chaos experiments. Nobody has ever signed a contract because of a vendor's GameDay program.
But the scoreboard is lopsided: done well, resilience is invisible no customer ever emailed to praise your failover. Done badly, it's the only thing they remember. Your customers can't tell the difference between a team that rehearses failure and one that doesn't until the day it matters, and by then they've already told everyone about the outage.
They never reward the skill
No renewal email has ever said “thank you for your excellent chaos tooling.” Customers reward the product. The resilience that protects it is expected, silent, and invisible when it works.
They always notice the absence
One bad outage undoes years of feature work. The story your customers retell is never “they have great tooling” it's “they were down for six hours.”
So it's for them, not for you
A GameDay isn't an engineering achievement to admire. It's how the product your customer depends on keeps its promise quietly, on a Tuesday, while you ship.
The GameDay was never for you. It's how your product keeps its promise.
What “undifferentiated heavy lifting” means for your systems
Amazon uses that phrase for work that is heavy, unavoidable, and identical at every company. Payroll. Email. Laptops that turn on. Building it yourself never makes your company different it just makes you the ten-thousandth team to build the same thing, slower and with more bugs.
Resilience testing belongs on that list. Every serious team needs to know its systems survive failure. Almost no team should spend months building the machine that finds out because the machine is the same one every other team ends up with.
What that means for your systems
The test never runs
Failovers stay untested. Retry budgets stay uncounted. Runbooks stay hypothetical. The crack is already in your system you just haven't met it yet.
The real outage keeps the advantage
A genuine failure picks the time (3 AM Saturday), the scope (everything at once) and the audience (your customers). A scheduled GameDay takes all three away.
Your best people work on the wrong thing
The engineers you hired for your product spend quarters writing dashboards for a fault-injection tool they'll use four times a year.
Plumbing is our problem. Product is yours.
You already outsource the boring parts
This isn't a new idea. It's how every serious company already operates. You just haven't applied it to resilience testing yet.
You don't build your own power station
You plug into the grid and get on with your day. Electricity is 'boring but essential', so someone whose entire job is electricity handles it.
You run fire drills. You don't manufacture fire extinguishers
The drill matters, not the equipment. Rehearsing an evacuation is what saves the building; nobody needs their own extinguisher factory for that.
Payroll, email, hosting, laptops that turn on
Every company runs on services someone else built. Not because they're easy, but because building your own would never make you different. It would just make you slower.
Build vs buy, side by side
Every team that starts building its own fault-injection platform ends up on the left. The interesting question isn't whether you could. It's whether you should spend your year there.
| Build it yourself | Oh My GDaaS | |
|---|---|---|
| Time to first GameDay | 6+ months of building, if it ships at all | Minutes, from one command |
| Ongoing upkeep | Every upgrade and dashboard is yours forever | Ours. You never patch a fault injector again |
| Safety guardrails | Build your own kill switch, blast-radius limits and aborts. Under deadline. | Included, tested, on by default |
| What it costs | Engineer-months you never get back | A subscription. Final prices announced at launch |
| What your best people do | Maintain plumbing | Build your product |
The homepage has a calculator that estimates how many engineer-hours your team is spending on resilience plumbing right now.
Being good at this doesn't help you sell widgets. Making sure your product keeps its promise does.
We built the plumbing so you never have to think about it again. That's the whole company.
