A lazygit-style TUI for PostgreSQL. Navigate schemas, run queries, view explain plans, peek at
pg_stat_*— without ever leaving the terminal.
Why?
I work in Postgres every day across a few projects (game backend, microservices, side projects). The existing tools are either:
- psql — terrific but no navigation, every operation is a
\d userscommand from memory - pgcli — REPL with autocomplete; better but still REPL-shaped
- pgAdmin / DBeaver / TablePlus / DataGrip — heavy GUIs, slow startup, some paid
- lazysql / Sqlit — multi-DB but shallow on each one; can't surface Postgres-specific stuff
lazygit proved how nice it is to navigate git visually inside a terminal. k9s did the
same for Kubernetes. lazydocker for Docker. No one did it for Postgres specifically.
pgcraft is that tool.
Postgres-only by design
This is not a generic SQL TUI. Going multi-DB means either shallow features or
abstracting away exactly the parts that make Postgres worth using —
EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON), pg_stat_*, partitioning, logical replication,
JSONB ops, vector indexes. The roadmap leans into those.
If you need multi-DB CRUD, lazysql is the right tool. pgcraft is for people who
actually live in Postgres.

Roadmap
- Phase 1 — TUI scaffold: layout, panels, vim-like navigation
- Phase 2 — Schema browser: schemas → tables → columns/indexes
- Phase 3 — SQL editor: write queries, execute, paginated results
- Phase 4 — EXPLAIN + search + Docker: EXPLAIN view, live filter (
/), multi-arch Docker - Phase 5 — Postgres-deep features:
pg_stat_user_tables,pg_stat_activity - Phase 6 — Launch: CI, GHCR Docker push, screenshots, HN announcement
- Future: partitioning view, JSONB tree explorer, replication monitor,
EXPLAIN (ANALYZE, BUFFERS), query bookmarks

Docker
# From source docker build -t pgcraft . docker run -it --network host pgcraft "postgres://localhost/mydb" # From GHCR (after Phase 6 release) docker run -it --network host ghcr.io/lucasfrederico/pgcraft:latest "postgres://..."
Multi-stage build → ~15MB final image (alpine + static binary).
ARM64 and amd64 supported via docker buildx.
Install
# Go install (any platform) go install github.com/lucasfrederico/pgcraft/cmd/pgcraft@latest # Homebrew (planned) brew install lucasfrederico/tap/pgcraft # Docker docker pull ghcr.io/lucasfrederico/pgcraft:latest
