Omnivore

• The SaaS version is free - as of 2024-09-23
• Not sure whether it can be called open source - all the code they have written is on GitHub, but apparently it has a dependency on commercial components (some PDF library) and is optimized for use with certain services (Google Cloud for hosting, Twilio SendGrid for receiving newsletters, S3 or compatible object storage)
