Show HN: JustComments – a comment system for websites

Since we are on Hacker News, it would be interesting to read something about the tech stack behind the product. After visiting your blog, I suppose you can tell, for example, how just-comments.com provides high availability with the help of AWS Kinesis, DynamoDB, Athena, etc.

By the way, this page is 404: https://just-comments.com/about.html (and some others from ToS)

Otherwise, congrats on the launch and good luck!

Thanks, I will fix the broken links :-)

The tech is completely hosted on AWS, and it is entirely "serverless". So the core is using the API Gateway + Lambda + DynamoDB. Additionally, I use Kinesis Firehose + S3 to process internally generated data such as billing events. Athena helps me to query the data if needed.

Basically, the scalability & high availability is entirely provided by AWS and the pricing model matches almost 1-to-1 the pricing by AWS.

If you have any specific questions about the tech, I can answer them.

If you match the pricing almost 1:1 / don't really make a profit, why don't you open-source it? Or do you actually make quite some profit by people who pay but don't really use their credits?

Just being curious about your plans

I match the model, not the price. I don't think you can make a profit from people who pay and don't use. Such people typically don't subscribe.

Generally, the project is none-free and low-margin and that is what makes it interesting. There are plenty of dead and alive open source projects offering comments which you can use.
