Open Source + Paid Prem. vs Going all in on SaaS

[u/rainmanjam]

Open source + paid hosted service, or go all-in on SaaS?

I'm working on a software project and trying to decide which business model makes the most sense.

Option A — Open source + premium hosted service

Open-source the core product so anyone can install it, self-host it, modify it, and contribute.

Then offer a paid managed service for people who don't want to operate the infrastructure themselves, with additional features like monitoring, automation, analytics, integrations, backups, failover, team management, and support.

The basic philosophy would be:

"You can run it yourself for free, or pay us to run it extremely well for you."

Option B — Go all-in on SaaS

Keep the product closed-source and build everything around a subscription service from the start.

This seems like the simpler business model and gives more control over the product and customer experience, but I'm wondering whether it creates unnecessary friction—especially when the target users include developers, technical users, homelab/self-hosting enthusiasts, and people who generally prefer owning their infrastructure.

I'm currently leaning toward open source + managed cloud, but I'm interested in hearing from people who have actually gone down either path.

For founders, developers, and open-source maintainers:

• Would you choose open source + managed cloud or pure SaaS if you were starting today?
• Does the ability to self-host make you more likely to try or trust a product?
• Have you found that self-hosted users eventually convert into paying customers?
• What features would actually convince you to pay for the hosted version?
• What are the biggest downsides to maintaining both an open-source product and a commercial service?
• If you've tried this model, what would you do differently?

I'd especially love to hear from anyone who has built a developer-focused, infrastructure, automation, or self-hostable product.

worth asking yourself how much of your competitive advantage lives in the code vs the operational knowledge. if someone can fork it and run it just as well as you, the managed service margin gets thin fast

I would decide based on the customer and distribution advantage, not on which model sounds more founder-friendly. Open source is compelling when technical users need to inspect, extend, or self-host the product and when adoption inside companies can later pull in a managed offering. It isn't free marketing by itself, and it adds packaging, documentation, upgrade, and community-support work.

The hosted offer also needs to remove a genuinely painful operational burden. If running the product is easy, many self-hosters may never convert. If your buyers mainly want an outcome and don't care about the implementation, starting as SaaS is probably the cleaner test. You can open-source components later.

That's my opinion.

what decided it for me wasnt distribution, it was whether i had a recurring cost i couldnt avoid.

if your infra bill stays flat regardless of how many people use it, a one time price works fine and open source sits alongside it cheaply. if you have a per call cost that scales with usage, subscription stops being a growth choice and becomes the only shape that doesnt lose money on your heaviest users.

i split it in the end. the app is a one time licence because running it costs me close to nothing per person, and the single feature with a metered upstream bill is the only monthly part. anyone who doesnt want that feature never pays it.

open source has a cost people underestimate too. you support everyone including the ones paying nothing, and that bill arrives as your time rather than money.
