Comparison Table
Astrolog
vertical specialistOpen-source astrology calculation program supporting natal, transit, synastry, and harmonic charts.
Aspect grid rendering tied to configurable orb and major-aspect settings for consistent review across repeated charts.
Astrolog provides natal chart generation with a calculation engine tuned for practical astrology workflows and exportable chart outputs. It supports multiple house systems and both tropical and sidereal zodiac modes so the same birth data can be recalculated under different frameworks.
Chart views include a natal wheel with aspects and an aspects grid that can be configured to match commonly used orb and major aspect settings. For people building repeatable chart studies, it also supports transits and synastry chart creation from the same core input fields.
- +Configurable house systems and zodiac modes for framework-specific recalculation
- +Natal wheel plus aspect grid views for fast cross-checking
- +Sensible orb and major aspect controls for consistent interpretation work
- +Synastry and transit chart creation from shared birth input
- –Less automation for batch processing and bulk chart studies than higher-tier tools
- –Limited visibility into calculation inputs when debugging mismatched results
- –Automation and API surface are not prominent for integrators
- –Geocoding and time handling depth can be thin for edge cases

How to Choose the Right Astrology Natal Chart Software
Options differ most in whether the output matches what you expect for your natal chart—especially when accuracy of calculations, chart customization, and export options vary. We suggest you compare using criteria like Calculation accuracy and House system options so the results stay consistent across tools.
Calculation accuracy for natal charts
Why it matters
Calculation accuracy for natal charts affects whether placements and houses line up with what other reliable charting tools show. If outputs drift, your later analysis becomes harder to trust.
How to check
Enter the same birth date, exact time, and location in two products and compare placements and house cusps. Use one or two well-documented example charts from the product’s own help pages, then confirm the numbers match the displayed reference.
Zodiac and house system options
Why it matters
Zodiac and house system options change the whole chart structure, so they must match your preferred method. If a tool limits choices, you may get “close” charts that still differ materially.
How to check
In settings, switch between available zodiac modes and at least two house systems. Recompute the same birth data and confirm the app updates placements and house cusps exactly as indicated in its explanation.
Time handling and time zone clarity
Why it matters
Time handling and time zone clarity matters because natal charts are sensitive to minutes near cusp changes. Tools that obscure conversions can produce unexpected chart shifts.
How to check
Input a birth time that is known to be sensitive (for example, near sunrise or a cusp event time you’ve used before). Check whether the product stores time zone explicitly and how it labels conversions in the chart summary.
Aspects and chart layers control
Why it matters
Aspects and chart layers control determines what gets computed and what’s visible when you review relationships. If settings are hidden or default too aggressively, you can’t reproduce what you saw.
How to check
Open the aspects or overlays panel and change a few basic controls like applying/separating behavior and orb scope if offered. Verify the on-screen aspect display updates immediately and that the chart export reflects the same settings.
Export formats and shareable outputs
Why it matters
Export formats and shareable outputs affect how you keep a consistent workflow from chart creation to sharing or documentation. If exports omit key settings, you lose reproducibility.
How to check
Export a natal chart in at least two formats (such as image and data/text). Re-open or import the output if supported, and confirm the export includes enough settings to match the original chart configuration.
Automation and API for chart generation
Why it matters
Automation and API for chart generation helps when you need repeatable chart production, batch work, or internal publishing. It also reduces manual transcription errors.
How to check
Look for an automation path: an API page, a CLI-like option, or documented import/export endpoints. Then ask for a quick demo that generates the same chart from provided inputs and returns the expected placements.
Red flags
- Outputs change when you switch settings, but the chart summary never shows what changed.
- House cusp or placement differences can’t be explained by your selected zodiac or house system.
- Exports omit the chart configuration, so a viewer can’t reproduce the same placements.
Fit by situation
- If you compare charts across tools to validate results, prioritize Calculation accuracy for natal charts.
- If you frequently switch methods between zodiac and houses, prioritize Zodiac and house system options.
- If you generate charts for multiple clients or pages, prioritize Automation and API for chart generation.
