# Open Source as Marketing
The most successful developer tools companies have figured out something the traditional software industry took decades to learn: giving your software away isn't charity, it's distribution.

HashiCorp, Elastic, Redis — all built massive developer adoption through open-source and monetized through enterprise features, support, and cloud hosting. The open-source version is a top-of-funnel lead generation engine.

For developer tools, open source has become so effective that a closed-source tool now carries an implicit trust deficit it has to overcome.

The economics of this model are worth examining in detail. Traditional software marketing requires spending money to acquire each user through ads, sales teams, or channel partnerships. Open-source marketing inverts this: the product distributes itself through GitHub stars, word of mouth, Stack Overflow answers, and blog posts by users solving real problems. Each user becomes a potential marketing channel. The cost of acquisition approaches zero at scale, which is why open-source developer tools companies can achieve adoption levels that would cost hundreds of millions in marketing spend through traditional channels.

But the model is not without tension. The companies that pioneered open-source-as-marketing are now navigating the uncomfortable transition from community darling to revenue-generating business. Elastic's license change, Redis's shift to dual licensing, HashiCorp's move from MPL to BSL — these are all symptoms of the same problem: cloud providers can take the open-source product, offer it as a managed service, and capture the monetization opportunity without contributing back. The marketing benefit of open source is real, but so is the risk of building a business on infrastructure that your competitors can freely use.

For smaller developer tools companies and indie hackers, the lesson is nuanced. Open source works brilliantly for distribution and trust-building, but the monetization strategy needs to be designed from the beginning, not bolted on later. The companies that navigate this well are the ones that clearly separate the open-source community value from the commercial enterprise value — things like team collaboration, SSO, audit logs, and managed hosting. The ones that struggle are the ones that open-sourced too much of the commercial value and then had to claw it back, damaging community trust in the process.

## Key insight
Open source is the most efficient distribution mechanism for developer tools ever invented, but it is a marketing strategy, not a business model. The distinction matters enormously. Companies that treat open source as their business model end up in a trap where they have massive adoption and no revenue. Companies that treat it as a marketing strategy — with a clear, pre-planned path to commercial value — build sustainable businesses on top of genuine community goodwill. The key decision is what to open-source (everything the individual developer needs) and what to keep commercial (everything the enterprise procurement team requires).
