that is open source

Plunk is open-source (AGPL-3.0) and self-hostable, while Loops is a proprietary SaaS platform. Plunk uses pay-as-you-go pricing with no contact limits, whereas Loops uses subscription tiers with contact-based limits. Both offer similar features, but Plunk gives you full transparency and control.

It depends on your usage. Plunk's pay-as-you-go model ($0.001 per email) means you only pay for what you send. Loops charges monthly subscriptions based on contact count. For businesses with variable email volume or growing contact lists, Plunk is often more cost-effective.
