💯 on Amanda’s suggestion with the free tier. All cloud providers offer a free tier and with AWS you get it for 12 months. You could e.g. use it to run a small EC2 instance with a local or docker agent entirely for free. One
community user used
replit.com for a hobby project hosting ECS agent, so there are a lot of opportunities here. I also have
this blog post showing how to set up an agent on ECS, and ECS really costs very little because you pay for only one container running your agent 24/7 rather than for an entire instance, and if you are on a free tier, this should cost you nothing.
