Build vs Buy: In-House Test Automation vs a Platform
Playwright/Selenium + CI pipelines you maintain vs. an autonomous reliability platform.
Continuously maintained. Content reflects current product capabilities.
TL;DR verdict
Build wins for small teams with narrow scope and strong automation culture. Buy wins when release risk spans multiple domains and toolchain maintenance shows up every sprint.
Two sides of the decision
Neither approach wins everywhere. Match the model to your risk profile and team capacity.
Buy: autonomous reliability platform
Zof maps your system, orchestrates agents across 19 domains, and produces reliability scoring with enterprise governance.
- Replace assembling Cypress + k6 + ZAP + BrowserStack + custom scripts
- System Graph context and cross-domain correlation
- SOC 2, SSO, RBAC out of the box
- Vendor cost and procurement
- Platform onboarding period
- Less fine-grained control than raw code for niche cases
Build: in-house stack
Open-source frameworks, internal frameworks, CI glue, and headcount to maintain it all.
- Full source control and customization
- No platform license line item
- Deep existing investment and skills
- Headcount scales with coverage domains
- Integration tax across tools
- No unified reliability model unless you build it
