Self-Hosting an Interactive Demo Tool: What the DigitalOcean Bill Actually Looks Like
Rendemo's Show HN launch has renewed a familiar debate: build your own interactive demo hosting or pay for a hosted tool. This piece walks through the three separate DigitalOcean pricing pages you need to check before you can total the real cost of self-hosting: object storage, compute, and a managed database. It also names who should stick with a hosted tool instead, based on how much maintenance your team can realistically take on.

Why Rendemo's Show HN launch matters for demo hosting decisions
A Show HN post for Rendemo pitches the tool as a way to make interactive product demos "easy," and the discussion it drew is a signal that teams are actively weighing hosted demo builders against making their own. If you're facing that same choice, the launch is a useful prompt to check what a self-hosted version would actually cost you to run before you decide either way.
The three DigitalOcean bills you would need to add up
A self-hosted interactive demo tool typically needs somewhere to store demo assets, a server to run the app itself, and a database to hold user and session data. DigitalOcean publishes separate, current pricing pages for each of those pieces, and none of them move together:
- Object storage — check DigitalOcean's current Spaces object storage pricing page before estimating what hosting demo recordings and assets will cost you.
- Compute — check DigitalOcean's current Basic Droplet pricing for a 2 vCPU / 4 GB instance to size the server that would run the application.
- Database — check DigitalOcean's current Managed PostgreSQL pricing if you plan to store demo and session data in a managed database rather than running your own.
Each of those pages updates on its own schedule, so a figure you saw quoted somewhere else may already be stale by the time you total a budget around it. Price all three at the same time, from the same source, before you compare the total against any hosted alternative.
Who should skip self-hosting entirely
If nobody on your team can maintain a Droplet, patch a database, and manage object storage lifecycle rules, a hosted demo tool is the lower-maintenance option even when it costs more per seat over time. Self-hosting only pays off once your usage is high enough, and steady enough, that the three DigitalOcean line items above land below what a subscription would charge you — and you will not know where that line sits until you have priced all three against your own expected traffic and storage needs.
