Does AstroPal use the same ephemeris as Astro.com?
Yes. AstroPal computes with the Swiss Ephemeris, which Astrodienst authored and maintains. On planetary positions the two agree, because it is the same underlying library.
The same ephemeris, configured for Jyotisha and explained.
The short answer
Where Astro.com (Astrodienst) falls short
In fairness, what Astro.com (Astrodienst) does well
Astrodienst, at astro.com, is the reference tool of serious astrology. It offers free high-precision chart calculation, an enormous archive of technical material, and options for practically every house system and ayanamsa in use. It is also the organisation that authored and maintains the Swiss Ephemeris.
The four pillars
AstroPal
AstroPal computes every chart with the Swiss Ephemeris in the sidereal zodiac. Lahiri is the default ayanamsa, with Raman, KP and Krishnamurti selectable. Twelve divisional charts from D1 to D30, planetary strength and the full Vimshottari mahadasha and antardasha tree are calculated for every birth, not just the D1.
Astro.com (Astrodienst)
We are not going to claim an accuracy advantage over Astrodienst, because AstroPal computes with the Swiss Ephemeris that Astrodienst wrote. On raw positional accuracy this is the same engine. What differs is the default posture: astro.com is a general-purpose calculator that will do anything if you know which options to set, while AstroPal is configured for Jyotisha out of the box, sidereal with Lahiri by default, and computes all 12 vargas and the full Vimshottari dasha tree without being asked.
AstroPal
One flat monthly price, and then nothing further. No per-minute meter, no per-report checkout, no charge for a follow-up question. The Kundali, Kundali Milan, Varshphal and baby name reports are free for everyone, PDF export included, and the entire Academy is open without an account.
Astro.com (Astrodienst)
Astro.com gives away chart calculation free, which is a genuine service to the field and always has been. AstroPal also gives away its Kundali, Kundali Milan, Varshphal and baby name reports free. The subscription is for interpretation, unlimited questions and the report library, which astro.com does not offer in that form.
AstroPal
Eleven full-length Vedic reports covering career, wealth, health, marriage, relationships, muhurat, numerology and Varshphal. Four are free forever. Every one is saved to your account, reopenable months later, and exports to PDF straight from the browser, with unlimited follow-up questions included.
Astro.com (Astrodienst)
This is the real difference. Astro.com sells a few interpretation reports as one-off purchases, but it is fundamentally a calculation and archive tool. AstroPal ships 11 long-form Vedic reports covering career, wealth, health, marriage, relationships, muhurat, numerology and Varshphal, four of them free, each saved to your account, reopenable and exportable to PDF.
AstroPal
Eight structured courses with ordered modules, lessons and quizzes, free and open without an account. They run from reading a first birth chart through yogas, Saade Sati, the Vimshottari dasha tree, nakshatras and planetary strength, so you can check the reasoning behind any answer rather than trusting it.
Astro.com (Astrodienst)
Astro.com hosts a large library of technical articles, much of it excellent and much of it written for practitioners. AstroPal publishes 8 structured courses with ordered modules, lessons and quizzes, designed for someone starting from nothing and ending up able to read their own chart. Different jobs: a reference library against a syllabus.
The reports
Every one is computed from your own chart, saved to your account, and downloadable as a PDF. Four are free forever; the rest are included with a paid plan.
Scroll for all 11. Kundali, Kundali Milan, Varshphal and the baby name report are free for everyone.

The verdict
AstroPal adds everything astro.com deliberately leaves out: Vedic defaults with no configuration, 12 vargas and the dasha tree computed automatically, plain-language interpretation, 11 saved reports with 4 free, and an 8-course syllabus. Astrodienst wrote the ephemeris we compute with, so positions agree; astro.com calculates, AstroPal interprets.
Yes. AstroPal computes with the Swiss Ephemeris, which Astrodienst authored and maintains. On planetary positions the two agree, because it is the same underlying library.
Because astro.com calculates and AstroPal interprets. AstroPal is configured for Vedic astrology by default, computes 12 divisional charts and the full Vimshottari dasha tree without configuration, explains the result in plain language, saves 11 reports to your account, and teaches the method through 8 free courses.
Yes, if you know which options to change: sidereal mode, the right ayanamsa and the right house system. AstroPal starts there, with Lahiri as the default and Raman, KP and Krishnamurti selectable.
