There are many computerized programs that can be used by the amateur and professional astrologer. I present here, in alphabetical order, the main programs for Western astrology (the programs for Indian astrology (Jyotisha) and Chinese astrology (Suanming) will be presented soon in different posts). 

Unlike noncommercial programs, all commercial programs have the ACS international atlas included, which makes the generation of horoscopes very fast, with no effort and time lost by the astrologer. 

Almost all important programs will be analyzed and compared in my astrology articles and courses so you can acquire them knowingly and make the most of their unique features. Of course, you can download any of the free programs as well as demo versions for almost all commercial programs so you can test them yourself. 

Commercial software for desktop

Aquarius – an Austrian commercial software, with a freeware version. Nice graphics and very easy to use interface. Useful for the practitioners of modern astrology (very few traditional features available). I particularly enjoy the ‘Horizon System’ function which lets you project a chart on the actual horizon using azimuth coordinates (very useful in horary, electional, mundane and geomantic interpretation). Prices between 79 and 119 EUR.

Almagest – a Russian software

Argus – a Danish software for modern astrology (with trial version). It seems to be overpriced.

Astrocalc – a program that integrates modern techniques. It comes in several editions, for different pockets. However, some free programs are better.

Astro Connect – a german software, with beautiful graphics. A bit too expensive for its capabilities.

Astro Gold Mac OS – probably the best application for Mac users, the software is very elegant and well-crafted; it looks similar with Solar Fire (but not as capable!). It’s files are fully compatible and interchangeable with Solar Fire desktop for PC, as well as Astro Gold iOS for iPhone and iPad. You can buy it for 180 USD (the professional reports are sold separately).

Astrology for Windows – a good program with interface in multiple languages.

Astro-PC – a remarcable French program with interface available in English, French, Italian and Spanish. I’ve tested the demo version and fell in love with it. It works on PC, but also on Mac with Windows installed. Outstanding graphics and capabilities! It can be used by the practitioners of classical, as well as modern astrology. It’s above many established commercial programs – unfortunately, it’s less well known and a bit steep: it’s basic version costs 330 EUR, the professional version – 530 EUR which makes it one of the most expensive astrology programs on the market.

Astroquick – a program with basic features. It works on PC, Linux and Mac OS.

AstroMart – a program with basic functionalities.

Astro Plus – a software in german language. At 350 EUR, the Pro edition seems very pricey to me.

Astroworld – a german software. I haven’t tested it yet.

Delphic Oracle – an excellent program, especially for Hellenistic astrologers. Probably the only one that integrates all the nuances of the ancient hellenistic techniques. It develops continuously as new discoveries are made at the origins of the astrological tradition.

Galiastro – a well known program in the Germanic-speaking Europe.

Interpid  a program focused on modern astrology. It runs on both Mac and Windows The price is $175

Janus – one of the best astrology programs available. It has excellent modules of natal, horary, medieval and cosmobiology calculating all the necessary charts, with the possibility of animating them. The modules include reports that can be edited by the astrologer.

Kairon – a modest software, for Macs. The price is € 100 for a full professional licence with full ACS atlas.

Kepler – a very good program with many important features. It provides very complex astrological reports that can be used commercially.

Mastro – Canadian software with a free version

Megastar – a Swiss program with menu in German; far too expensive compared to what it can do!

Millennium Star Trax – a very ingenious program offered by AIR Software, although the interface deși interfața lasă de dorit.

Nova Chartweels – a powerful software from Astrolabe with special graphics and drag & drop features. Price: $220

Pegasus – a lite version of Kepler

Placidus – an excellent program of ancient (Babylonian and Hellenistic) and medieval astrology from Rumen Kolev. From what I hear, the capabilities of this program are great! The software is now distributed through Astrolabe and is one of the best program for antique and medieval astrology on the market (competing only with Delphic Oracle).

Placidus 4.1 – probably the most renowned Hungarian software, with a free version. It looks a bit like the free software Morinus.

Phasis – an amazing Italian classical (Ptolemaic) astrological program, functional on Windows and Mac, in English and Italian.

Prometheus – a recently released program with nice graphics (including 3D). It’s getting better and better.

Regulus – although it’s specialized in the Huber system, it has important capabilities in traditional approaches.

Sarastro – a program with complex functionalities and a very pleasant interface in German. Proces between € 100 and € 300.

Sirius – includes all of Kepler’s features, but also adds some advanced features. An excellent program for astrological research! In competition with Solar Fire, Sirius is one of the best astrology programs!

Solar Fire – the most widely used professional astrology program. It has a very nice interface and excellent features, it offers all the working capabilities, many calculation options, a wide variety of chart formats, including superb animations and graphics and well-written reports. Even a simple enumeration of the basic features would take too much space (and time) to be appropriate here.

Time Cycles – a software exclusively for Mac. It has several modules that can be purchased separately

TimePassages – very intuitive and easy to use, with excellent design, but very expensive. It can run on both Windows and Mac OS. It can be used by astrologers who only use the modern techniques of “modern” astrology (transits, progressions, solar and lunar returns, sinastry, mid-points, etc.), so it does not integrate the important features of traditional astrology, which – in my opinion – is an inconvenient disadvantage for any astrologer to take seriously!

Vision – a program known especially on the German-speaking market. 

Winstar – probably among the first commercial astrological programs in the world and one of the best currently available, a product of over 35 years of continuous development. Prices between $180 and $360

Zet – an outstanding Russian program. Prices between $ 100 and $160 

Free software for desktop

Astrolog – the object of the nostalgia for many astrologers around the World. It was good, it was free (it’s still good, it’s still free!). Functional on all major platforms (Windows, Mac, Unix). There are several variations of the original version on the market.

My advice

If you want a program for your private or professional practice, choose knowingly! It’s good to understand what each one can do and whether it meets your needs, integrates the techniques and approaches you use, and matches the technology you have at your disposal. At the same time, the program should give you the opportunity to do astrological research and to experiment with techniques that are not yet familiar to you. A program should be simple and easy to use, make your work easier and not throw you in the fog!

Many programs (especially commercial) try to meet all needs, but sometimes include a wealth of very strange techniques and approaches that don’t have a solid theoretical foundation nor the support of the astrological tradition. For me, an alternative option is (was) to use several free programs that make different things and complement each other. If you can overlook the discomfort and the lost time with entering the data in each program, this may be an option that will save you money. There are many good, free programs that – taken together- cover the practical needs of the most sophisticated astrologers!
