TigerFS Mounts PostgreSQL As Transactional Filesystem
TigerFS, an open-source project announced April 4, 2026 by TigerData CTO Michael Freedman, mounts a PostgreSQL database as a POSIX-like filesystem and stores rows as files with ACID guarantees. The MIT-licensed tool supports file-first and data-first workflows, mounts via FUSE on Linux and NFS on macOS, and exposes database data to standard Unix tools for developer and agent workflows.
Key Points
- 1Mounts PostgreSQL as a filesystem, mapping each row to a file with ACID guarantees.
- 2Provides file-first and data-first workflows to support editors, CLIs, concurrent agent coordination.
- 3Enables immediate tooling: mount via FUSE/NFS for direct use by developers and AI agents.
Scoring Rationale
A practical, usable open-source tool from the project founder earns high actionability and credibility; scope is focused on developer and agent workflows so novelty and breadth are moderate. Timely release adds slight positive adjustment.
