Founder here - We recognize that Slack certainly isn't for everyone which is why everything also works in our CLI and also soon by public API. Slack have a great uptime and regularly stay above 99.9% uptime according to their status pages - that said, if you wanted to bypass Slack and still run cloud native workflows using CTO.ai, serverless-ly, we allow you to also do that via CLI or API. This means you could build your own client and just leverage us for inexpensive compute.
Thanks for sharing your feedback!
