The piece lays out the hidden costs of building in-house (ongoing maintenance, security debt, opportunity cost) versus buying, using real anecdotes like a site going down because a domain lapsed or an AWS account tied to a canceled AMEX card. It closes with seven practical criteria for deciding whether to build or buy: competitive advantage, familiarity with the tech, tolerance for downtime, blast radius if hacked, compliance requirements, willingness to run open source, and whether adequate buy options truly don't exist. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I decide whether to build a tool in-house or buy a SaaS product at my startup? Build only if the system is part of your competitive advantage or closely resembles what your team already maintains well. Buy if you cannot tolerate downtime, if a breach would be catastrophic, or if compliance requirements like HIPAA, GDPR, SOC 2, or PCI apply, since SaaS vendors spread that overhead across many customers while an in-house build leaves you bearing the full cost alone. _Engineers weighing infrastructure trade-offs follow real-world build-vs-buy debates on daily.dev._ ### What are the hidden costs of building internal tools instead of buying them? Building creates ongoing maintenance burden long after the initial excitement fades, since the original developers often move to other projects or leave the company entirely, leaving ops teams to run unfamiliar services in many different languages. One example involved dozens of home-built websites accumulating security vulnerabilities, with incidents like a site going down because a domain lapsed after its owner left the company. _Teams debating infrastructure ownership can track similar engineering trade-off stories on daily.dev._ ## Similar posts on daily.dev - [Build vs Buy When Building Just Got Cheap](https://daily.dev/posts/build-vs-buy-when-building-just-got-cheap-bxumyqpbm) · Tech Lead Digest · 0 upvotes · 0 comments - [Build vs. Buy Guide for Internal Developer Platforms \(IDPs\)](https://daily.dev/posts/build-vs-buy-guide-for-internal-developer-platforms-idps--z8vdqyugu) · Spacelift · 0 upvotes · 0 comments - [Custom web application development: build vs buy](https://daily.dev/posts/custom-web-application-development-build-vs-buy-bqeoem5gt) · Netguru · 1 upvotes · 1 comments - [Build vs. Buy Your Kubernetes Development Environment](https://daily.dev/posts/build-vs-buy-your-kubernetes-development-environment-vjhfexmfg) · MetalBear · 9 upvotes · 0 comments - [Is the ‘SaaSpocalypse’ a myth?
