TimePassages alternatives.

TimePassages is AstroGraph’s natal software: desktop editions for Windows and macOS, plus iPhone and Android apps and a TimePassages 3.1 web app at astrograph.com. One login syncs charts across iPhone, Android, and the web. You enter a birth date, time, and place; it draws a chart and lets you click a planet or aspect for interpretations written by Henry Seltzer. People still look for alternatives because they want a no-account preview, a Swiss Ephemeris web form, or beginner prose. Those are different jobs. This note does not rank a winner.

The options, with tradeoffs

1. TimePassages (AstroGraph) — AstroGraph’s desktop, mobile, and TimePassages 3.1 web app: natal, transits, synastry, and click-to-read interpretations by Henry Seltzer, with one login across iPhone, Android, and the web.
   Good for: Practitioners and students who want software they can keep, with house-system switches — Placidus, Koch, Whole-sign, Equal, Campanus, Porphyry — and a built-in city atlas.
   Tradeoff: Desktop, mobile, and the 3.1 web app are signed-in, not Charting Stars’ no-account browser Big 3. Desktop editions still exist for Windows and macOS; mobile and web share that login rather than a no-account preview.
2. Charting Stars — A browser observatory: enter birth date, time, and place and get a free Big 3 — Sun, Moon, and Rising — with no account required.
   Good for: A timezone-correct natal from VSOP87 positions and IANA historical zones, then an optional paid Hellenistic reading from that same birth moment.
   Tradeoff: Whole-sign is the house system, and the free preview is the Big 3, not the full planet/house/aspect tables. If you need Placidus for a client file, stay on TimePassages or Astro.com.
3. Astro.com (Astrodienst) — The long-running web chart service from Astrodienst: Swiss Ephemeris positions, many house systems, many chart types, and optional human-written reports.
   Good for: Students who already know which house system they want and need a technical wheel they can print, without installing desktop software.
   Tradeoff: The form is dense and the interface is older than a phone natal app. It will not keep a local chart file the way TimePassages does, and the deeper reports are paid.
4. Cafe Astrology — A natal calculator paired with a large library of beginner articles for each planet-in-sign and house.
   Good for: A gentle first reading of placements, one paragraph at a time, without a TimePassages login or an Astro.com options form.
   Tradeoff: The text describes placements individually. It does not synthesize a whole chart the way a written reading or practitioner software does.
5. Astro-Seek — A large free suite of calculators: natal, synastry, composite, transits, progressions, and more.
   Good for: Enthusiasts who already know which chart they want and need the math, not a guided essay or a signed-in TimePassages account.
   Tradeoff: The interface is a workshop, not a first lesson, and the interpretations are thinner than TimePassages’ click-to-read copy.

How to choose

Pick TimePassages if the job is software you keep — natal, transits, and point-and-click interpretations on desktop, phone, or the signed-in 3.1 web app. Pick Astro.com if the job is a Swiss Ephemeris wheel and a house-system menu. Pick Cafe Astrology if the job is beginner placement copy. Pick Astro-Seek if the job is a calculator workshop.

Pick Charting Stars if the job is a self-serve natal in the browser — VSOP87 positions, IANA timezones, no account to generate the Big 3 — and you may later want a written reading from that same birth moment.

These tools can sit next to each other. A TimePassages alternative is not a claim that AstroGraph failed; it is a different instrument for a different job. Co-Star and CHANI live in a further neighborhood: daily-ritual phone apps, not practitioner software.
