Looking for an Astro-Seek alternative?
Astro-Seek describes itself as free astrological tools and calculators for both beginner and advanced astrologers, and its tools menu alone lists fourteen. OrbHeaven does a fraction of that and explains what it does as it goes, then turns the chart into dated periods ahead and a record of how they went.
OrbHeaven vs Astro-Seek
This is the closest comparison in the set, and not in the way you might expect. Most of these pages turn on whether a product will tell you how it calculated something. Astro-Seek will — it puts a zodiac selector and both node conventions on its own front page. The real difference is that it hands you a workshop, and we hand you one finished thing with the labels still on.
| What is being compared | OrbHeaven | Astro-Seek |
|---|---|---|
| How each describes itself | A chart, a calendar and a record you build over time | "Free astrological tools and calculators for both beginner and advanced astrologers" |
| Breadth of tools | One natal chart, explained term by term, plus a dated timeline | Fourteen named tools, including ephemeris tables for 1800–2100, AstroCartography, electional calculators and several search engines |
| Conventions shown to the reader | Yes — astronomy-engine 2.1.19, Placidus, and the exact universal time, printed on the chart | A zodiac selector on the front page, and both the mean and the true Node listed separately |
| Every term explained where it appears | Yes — 46 glossary entries, linked from the chart itself | Not published on their site |
| Advertising | None. No ads, and no third-party ad scripts | Third-party display ads on the page |
| Price | Free tier that keeps working; Plus is $12 per month | Free to use, with a free account offered. No pricing page found |
Every Astro-Seek detail above comes from Astro-Seek’s own website or support pages, checked on 24 September 2026. Where a cell says “not published on their site”, we could not find the answer published by the company itself and chose to leave it blank rather than guess.
What Astro-Seek does well
The free tool set is large. Ephemeris tables covering 1800 to 2100. AstroCartography. Electional calculators for picking a moment. Search engines for finding when a particular aspect occurred, or a return on a particular degree. A monthly and an annual astro calendar. Its tools menu alone names fourteen. OrbHeaven has none of those.
It is clear about who it is for: free tools and calculators “for both beginner and advanced astrologers”.
It also shows its conventions. Its front page carries a zodiac selector, and it lists the mean Node and the true Node separately rather than silently picking one — the same node convention disclosure OrbHeaven argues for. Transparency about method is therefore not a point of difference between these two products, and this page does not claim it as one.
How OrbHeaven approaches astrology
We do much less, and we explain it. One natal chart, computed locally by an open astronomical engine, with the engine name and version, the house system, the node convention and the exact universal time printed on it. Birth times convert using the historical time zone rules for that place, a birth time the clocks repeated or skipped is asked about rather than guessed, and where the birth time is unknown the Ascendant and the houses are withheld rather than guessed. Clock times are converted using the international time zone database. Historical timezone records are strongest from 1970 onward; earlier records can be less certain, particularly where local clocks differed from a region’s recorded standard.
The effort that Astro-Seek puts into breadth, we put into the layer above the arithmetic. Every term on the chart links to a plain-language definition, and where astrologers genuinely disagree the definition says so instead of quietly choosing. Interpretation is written by a language model reading the engine’s output — never computing it — and labelled as such.
Then something different again: the chart becomes a calendar of dated stretches ahead, and when one has passed the product asks how it actually went and keeps the answer.
The differences that actually matter
A workshop, or one finished thing
Astro-Seek’s tools menu alone runs to fourteen entries, and that is one menu of several. OrbHeaven offers one chart and one timeline, which is worse if you know exactly what you are after and better if you do not.
Who pays, and how
Astro-Seek is free and carries third-party display advertising. OrbHeaven has a permanent free tier and a subscription, and carries no advertising at all. Neither model is nobler. Ads keep a large free toolbox running; a subscription means the only person the product answers to is the person using it.
Explained where it appears
Both of us will tell you which conventions produced a number. OrbHeaven also explains, on the chart itself, what each convention is. If you already know the difference between the mean and the true Node, that explanation is wasted on you, and Astro-Seek’s breadth is the more useful thing.
A chart, or a record
Astro-Seek calculates something each time you ask. OrbHeaven is built to accumulate: dated periods ahead, a check-in when each one passes, and your own answers read back to you months later. That is worth nothing on day one and is the whole point by month six.
Who might prefer Astro-Seek
- You already read charts and want the specific tool, not an explanation of it.
- You need ephemeris tables, AstroCartography or an electional calculator — we have none of those.
- You want to search for when an aspect occurred, rather than be told.
- You would rather see an advert than pay for anything, which is fair.
Who might prefer OrbHeaven
- You can read a chart but were never taught what the conventions behind it mean.
- You want dated periods ahead rather than a calculator to point at a date.
- You want the thing to ask how a period went and keep your answer for later.
- You would rather no advertising sat next to your birth details.
These two overlap less than they look. Using Astro-Seek for the tool work and OrbHeaven for the calendar and the record is an entirely sensible arrangement, and not one we would argue you out of.
What are the alternatives to Astro-Seek?
These products offer chart tools in different shapes, so they are listed by what you might want rather than ranked. We make the last one, so weigh that entry accordingly.
Astro.com (Astrodienst)
If you want another wide range of free chart tools in a browser. Its free tools include chart drawing with the Ascendant, an extended chart selection, an astrology atlas and ephemeris creation, and it publishes a 9000-year ephemeris. It asks you to register the first time you create a horoscope.
Cafe Astrology
If you want a free chart report with written interpretations. Cafe Astrology’s free birth chart tool lists planet signs, house positions and aspects, lets you compare several house systems, and says its default house system is Placidus. Its interpretations of many of the major factors, such as the Sun, Moon, Ascendant, Mercury and Venus in signs and houses, are written by the site’s author.
Astro Gold
If you want many chart types, house systems and zodiacs in installed software. Astro Gold’s App Store listing describes natal and transit charts, and at its paid Gold level progressed, directed, solar return, lunar return and composite charts. It says it supports many house systems and sidereal zodiacs, covering dates from 1200 BCE to 2400 CE. Its website lists versions for macOS, Windows, iPhone and iPad, and Android. It is free to download, with the Gold level available by monthly subscription or a one-time purchase.
TimePassages
If you want chart software with written interpretations, on your computer or phone. TimePassages, from AstroGraph Software, is available for Windows, macOS, Android and iPhone. It covers the birth chart, transits, progressions and chart comparison, and its maker says every interpretation is written by experienced astrologers.
OrbHeaven
If you want each part of a chart explained as you read it. OrbHeaven is ours, and it does far less than Astro-Seek. Its free chart needs no account, stores nothing and carries no advertising, and every term on it links to a plain-language definition. Signed in, it sets out dated stretches ahead, each with a beginning, a peak and an end, and when one has passed it asks how it went and keeps your answer.
If you would rather have an app built around daily astrology than chart tools, there are comparisons with Co–Star, The Pattern and CHANI. For the wider field, organised by what you want, there is a round-up of astrology apps and platforms, and every comparison we have written is collected in one place.

Questions people ask
Is OrbHeaven an Astro-Seek alternative?
For casting and understanding one chart, yes. For the rest of what Astro-Seek does — ephemeris tables spanning three centuries, AstroCartography, electional calculators, aspect and ephemeris search engines — no, and we have no plans to be. If the tool you open Astro-Seek for is one of those, nothing here replaces it.
Which one is more transparent about how the chart is calculated?
Both are, and this is the one comparison in our set where that is true. Astro-Seek puts a zodiac selector and both the mean and the true Node on its front page, which is exactly the kind of disclosure we argue for. OrbHeaven states the engine and version, the house system, the node convention and the exact universal time on the chart itself. The difference between us is not honesty about method — it is that OrbHeaven explains what those choices mean in plain language, on the chart itself.
Does either one show ads?
Astro-Seek carries third-party display advertising. OrbHeaven carries none — no ads, no ad scripts, and no plans for either. That is a real trade-off rather than a criticism: ads are how a free toolbox at that scale stays free, and we chose a subscription instead.
Do I need an account for either?
OrbHeaven's full chart at /birth-chart needs no account, no email address, and stores nothing you type. Astro-Seek's tools are free to use and it offers a free account as well; we have not verified which of its tools, if any, require one.
What does Astro-Seek cost?
We could not find a pricing page on their site, and we are not going to state a price we have not seen. The site is free to use and carries advertising. If they do have a paid option somewhere, it is not where we looked.
What does OrbHeaven do that Astro-Seek does not?
Two things. It explains every term where it appears, so reading the chart does not require already knowing what an orb or a stellium is. And it keeps a record: when a period it flagged has passed, it asks how it actually went, holds your answer, and reads the whole thing back to you later.
