48% of tracked AI tools depend on two providers — OpenAI and Anthropic combined. If either raises prices significantly, changes their API, or has a significant outage, nearly half of the AI tool ecosystem is affected.
This is not a risk prediction. It is a verified measurement computed from active integration relations tracked on sourc.dev.
What Blast Radius Score measures
The BRS measures how many downstream entities are affected if a given entity has a significant incident. A high BRS means many other entities depend on this one.
How to use this for vendor decisions
Before adopting an AI tool, three questions worth answering:
What is the entity’s BRS? High BRS means the entity is a critical dependency for many others — less likely to disappear, but more affected when it has issues.
How many certified integrations does it have? More certified integrations = more embedded in the ecosystem.
What is the provider concentration? If a tool only supports one model provider, you inherit that provider’s risk entirely.
Building a stack with lower concentration risk
For each AI component in your stack, identify the alternative that could replace it within 30 days. If no alternative exists, that component is a single point of failure.
