Hey guys,
I’d like to share an open-source email archiving tool I’ve created.
So the backstory is that I run a small software company here in Estonia, and we use Google Workspace for all of our emails and financial documents. One day, I had this paranoia that what if we lost access to our Google Workspace due to some vendor abnormalities (which is not even rare to happen).
So I built this open source tool that helps individuals and organizations to archive their whole email inboxes with the ability to index and search these emails.
The tool is called Open Archiver, and it has the ability to archive emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and all IMAP-enabled email inboxes. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage).
Some features:
- Archive and index all emails and attachments
- Back up the whole organization's emails: For Google Workspace and MS 365, Open Archiver can import and sync all individual inboxes' emails
- Full-text search: All archived emails and attachments are indexed, so you can search all emails and attachments from Open Archiver's web UI
- You can choose to store your files either on your local machine or on any S3-compatible storage provider
- API access
Since it's an open-source project, you can use it for free for individual or business purposes. I’d be happy to connect with you and hear your feedback in our Discord channel. You can find the invite link in the README file.
You can find the project on GitHub (Demo site available): https://github.com/LogicLabs-OU/OpenArchiver
Disclaimer about the use of AI: I've noticed that there is an ongoing discussion on this sub about projects using AI. I'd like to point out that some of the code in the project is written with the help of AI. However, the use of AI is limited to coding assistance, as I myself am a full-stack developer with 5 years of experience. Here is how I used AI in the project:
- Writing some frontend components
- Writing boilerplate code for API routes and controllers, while the logic of the services are hand coded
- Writing comments to help other developers understand the codebase
- Writing docs
- Most importantly: all code generated by AI is carefully reviewed and scrutinized to the same level as how we build other commercial products
I understand it is the sub rules to disclose AI involvement in development, so I added this disclaimer. Please let me know if you have any concerns.
Cheers!
