Ask HN: Good devcontainer/remote dev environment?

I've been curious and have been asking around a bit locally but thought it might be worthwhile checking here too.

Has anyone tried a devcontainer / remote dev / ... or related setup that worked really well?

I think my ideal would be something that can easily switch between local, if I'm on a train, and remote dev, for more resources than my laptop has.

- SSH connections or sshfs dies whenever I close the laptop lid to carry it to a meeting.

- Remote desktop solutions never seem to work as smoothly or nice as local.

- I tried github codespaces once but it seemed "meh".

- Containers often take a while to build, especially when sent off to somewhere, impacting feedback loop / iteration time. At a previous job building a whole pipeline took about 40min, and then running it took another 20. So you had about 8 attempts per day to try something.
