Bootstrapped founders building connected products face a hard choice: either the device depends on the server for everything, or you build a data converter that stays in sync forever. The device keeps readings and settings in its own format. The server wants those same values as database rows. Somebody writes a converter. Then somebody has to keep that converter alive, correct, and tested for ten years. Meanwhile, every format change on the device breaks things on the server, and every connection hiccup means retries and conflict resolution.

Bootstrapped founders know the math: every service you pay for is a monthly line item that has to be justified by revenue. The reverse proxy sits in front of your whole business, so it has to be reliable, but you don’t want to pay for a managed service you don’t need. You also don’t want to spend months learning nginx config syntax only to discover nobody on your team understands what you built.

Bootstrapped founders know that every line item in your SaaS bill cuts into profit. The hosted analytics service you signed up for looked cheap at first, but now you’re paying per gigabyte ingested, per query, per custom metric. You’ve got months of customer data, but you hesitate before running a new analysis because you know it will cost money. Meanwhile, you still don’t have the dashboards you actually need.

The other approach is to build analytics from scratch. You recalculate numbers on every dashboard refresh, which is fine until you get actual traffic. Then every refresh becomes slow, and every slow dashboard is a feature you’re not shipping because you’re spinning waiting for a query.
