Build vs Buy
Weigh building a feature in-house against buying a third-party service, scored against your own priorities.
The numbers: cost over time
One-time setup versus ongoing fees — see when, if ever, one path becomes cheaper than the other.
Simplified, linear model — assumes steady maintenance hours and a flat license price over time. Treat the break-even year as a rough signal, not a forecast.
The priorities: how each path scores
Cost is only one lens — weigh it against control, speed to ship, and ongoing maintenance overhead below.
How much do you care about each of these?
For the priorities you selected, Buy / integrate scores highest — driven mostly by speed to ship.
What would change this: Build in-house scores higher on control & customization — raise that priority enough and it can overtake Buy / integrate.
| Dimension | Your weight | Buy / integrate |
|---|---|---|
| Cost Efficiency | 5/10 | 7/10 |
| Control & Customization | 5/10 | 4/10 |
| Speed to Ship | 5/10 | 9/10 |
| Low Ongoing Maintenance | 5/10 | 7/10 |
Where do these scores come from?
Editorial 0–10 assumptions based on general build-vs-buy tradeoffs — building typically wins on control but loses on speed and maintenance burden; buying is usually the reverse. Your specific situation (team size, budget, how core this is to your product) can easily flip these.
Understand Build vs Buy
What this tool helps you understand
Set your priorities across cost, control, speed to ship, and ongoing maintenance, and get a transparent, weighted comparison of building the feature yourself versus integrating an existing service.
When to use it
Use Build vs Buy when engineering, projects, and money work raises questions about build vs buy, make or buy decision, and third party vs in house and you need a concrete view before making the next move.
How to read the result
Treat the leading option as the best fit for the priorities you selected. Review the score breakdown before acting because changing those priorities can change the result.
Assumptions and limits
The comparison uses transparent editorial scores and the priorities you choose. It supports a decision; it does not prove that one technology or approach is objectively best.
