I been sleeping on #secretspec. 😅 It has now support for composite secrets! Think multi secrets put together in one string. The killer feature for those DATABASE_URL all over the place. 😛 secretspec.dev/concepts/com...

Where .env Went Wrong
A local convenience became a secrets interface, an environment model, and a deployment format. It was never designed to be any of them.

SecretSpec 0.17 is out. Give each service only its declared secrets with scopes, cache slow remote providers locally, cross-secret validation. 20 providers, this release adds: SOPS, age, KeePass KDBX, OpenBao, Scaleway, systemd credentials. Also, GitHub Actions. secretspec.dev/blog/secrets...

Declare secrets once. Store them anywhere.
Declare what your application needs in secretspec.toml — store the values in any of 11 backends. No secrets in git. Same code, every environment.

I've really been enjoying the `devenv` tools for `nix` environments. I've also made it so that AI agents for projects by default must use the `devenv` environment. It's not hardened or anything, but it is nice to be able to destroy environments safely on demand.

Typically, cross-project sharing of best practices is done using scaffolding. It doesn't have to be that way - you can keep those in sync across monorepo or polyrepo setup by extending our modules. New guide: devenv.sh/extending/
