Framework choices

Trade-offs for your team and timeline.

Data & infra

Databases, hosting and services that fit your scale.

Build vs buy

When to ship fast on a service and when to own it.

In context

Recommendations grounded in your stack and memory.

Frequently asked questions

How does newtools recommend a stack?
The CTO agent compares your options against your actual use case, team and stage, and tells you what to build on, buy, or skip — grounded in your context.

Yes. Recommendations factor in what you've already built on, so they stay compatible.
Can it help with build-vs-buy?
