Feature comparison
Frequently asked questions
What is the main difference between Sendwave and Loops?
Sendwave is open-source (AGPL-3.0) and self-hostable, while Loops is a proprietary SaaS platform. Sendwave uses pay-as-you-go pricing with no contact limits, whereas Loops uses subscription tiers with contact-based limits. Both offer similar features, but Sendwave gives you full transparency and control.
Is Sendwave cheaper than Loops?
It depends on your usage. Sendwave'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, Sendwave is often more cost-effective.
Can I self-host Sendwave unlike Loops?
Yes. Sendwave is open-source and can be self-hosted using Docker. This gives you full control over your data, infrastructure, and costs. Loops is cloud-only with no self-hosting option.
Does Sendwave have the same modern features as Loops?
Yes. Sendwave offers transactional emails, marketing campaigns, workflow automation, dynamic segmentation, and a modern API, just like Loops. The key difference is Sendwave is open-source, self-hostable, and has no contact limits.
How easy is it to migrate from Loops to Sendwave?
Migration is straightforward. Export your contacts from Loops, import them to Sendwave via CSV, and update your application to use Sendwave's API. Most migrations can be completed in a few hours.
