    Show HN: Claudespace – Run isolated Claude Code instances locally

    We built Claudespace to avoid conflicts when running Claude Code alongside our dev flow. It uses git worktrees, remapped ports, and env isolation to spin up multiple local instance…

    It probably uses a HyperLogLog--the 2% error rate kind of gives it away. Bloom filters approximate set membership queries, HyperLogLogs approximate set cardinality queries. COUNT D…
