hledger is a computer program for easily tracking money, time, or other commodities, on unix, mac and windows (and web-capable mobile devices, to some extent).

It is first a command-line tool, but there is also a web interface and a Haskell library (http://hackage.haskell.org/package/hledger-lib) for building your own programs and scripts (hledger is written in Haskell). hledger was inspired by and is largely compatible with Ledger. hledger is free software available under the GNU General Public License v3+.

hledger aims to help both computer experts and regular folks to gain clarity and control in their finances and time management, but currently it is a bit more suited to techies. I use it every day to:

• track spending and income
• see time reports by day/week/month/project
• get accurate numbers for client billing and tax filing
• track invoices

Though limited in features, hledger is lightweight, usable and reliable. For some, it is a simpler, less distracting, more future-proof alternative to Quicken or GnuCash.
