Why We Chose Self-Hosting Over Cloud APIs

While building PolyTalk, one of the biggest decisions we faced was whether to rely on cloud APIs or keep everything self-hosted.

At first, cloud services seemed like the obvious choice. They make it easy to get started and remove a lot of operational overhead.

But the deeper we got into the project, the more we realized that self-hosting wasn’t just a deployment preference, it was a requirement for many of the use cases we were exploring.

A few things we learned along the way:

• Running speech recognition, translation, and TTS locally is absolutely possible, but latency quickly becomes one of the biggest engineering challenges.
• Supporting multiple audio sources (microphones, meetings, browser tabs, system audio, etc.) is often more complicated than the translation itself.
• Choosing models is a constant trade-off between quality, speed, hardware requirements, and language coverage.
• Privacy, compliance, and data sovereignty concerns came up far more often than we expected when talking to potential users.

Self-hosting definitely isn’t the easier path. You have to think about infrastructure, updates, monitoring, and resource management.

That said, the trade-off is greater control over your stack, fewer external dependencies, and more flexibility in how the system is deployed and operated.

For us, those benefits were worth the extra complexity.

I’m curious how others in the self-hosting community think about this.

When do you decide a service is important enough to self-host instead of relying on a managed API or SaaS provider?

For anyone interested, PolyTalk is the project that led us down this rabbit hole:
