senv Overview
Pros
- β’ Real OS-level security boundary under a familiar uv workflow; teammates can keep using uv unchanged.
- β’ Deny-by-default network and a read-only runtime at run time prevent supply-chain persistence and credential leakage.
- β’ Secrets are declared explicitly and are never visible to install-time build code.
- β’ Trust model (`senv trust`) stops a compromised dependency from silently widening the policy for future runs.
- β’ Apache-2.0, free, single Rust binary; installs via curl, `uv tool install h5i-senv`, pipx, or `cargo install`.
Cons
- β’ Very early: v0.1.0, ~43 stars / 5 forks, last push 2026-08-15 (about a month quiet at time of review).
- β’ Niche: only valuable if you run untrusted Python β agent-generated code, third-party deps β and care about supply-chain/runtime isolation.
- β’ Requires uv on PATH; Linux needs slirp4netns + nftables, Windows is WSL2-only, so setup is not zero-config everywhere.
- β’ Adds a learning curve (senv.toml policy, `senv trust` prompts) versus plain uv for everyday work.
- β’ Pre-1.0: CLI/behavior may still change; community and battle-testing are minimal.
