Astro.com is the best pick for individual users who need consistently shareable natal reports, because its PDF exports preserve the chart wheel layout and aspect grid details for reliable offline viewing. Janus is the alternative for practitioners who want repeatable desktop natal-to-PDF delivery, since report-focused wheel rendering and fast recalculation keep outputs uniform.

Comparison Table
Astro.com
vertical specialistOnline birth chart software with Swiss Ephemeris calculations and extensive chart options.
PDF chart export that preserves the chart wheel layout and aspect grid details for consistent offline sharing.
Astro.com is a long-running natal chart generator that uses Swiss Ephemeris-based calculation for planetary positions.
It supports multiple house systems such as Placidus and whole sign and renders chart wheel style reports with aspect grids.
Computed results can be exported for offline sharing through PDF chart export, which keeps visual chart details and tabular aspects together.
Programmatic automation is not a primary offering, since there is no documented automation or API surface for batch chart generation.
- +Swiss Ephemeris-driven position calculations with consistent chart outputs
- +Multiple house systems available during chart setup
- +Chart wheel reports and PDF chart export for sharing
- +Detailed aspect grid output supports applying and separating aspect checks
- –No public API surface for automation or workflow integration
- –Birth time rectification tooling is limited compared to specialized software
- –Whole-sign and quadrant house options are present but not deeply configurable
- –Bulk generation and governance controls for many users are not built for teams

Best for: Fits when individual users need accurate natal chart reports with exportable PDFs and quick recalculation.
TimePassages
vertical specialistAstrology software for desktop and mobile that generates detailed natal charts with interpretive reports.
Printable natal chart reports with PDF chart export from a saved birth profile.
For natal chart production, TimePassages takes birth date, birth time, and location inputs to compute planetary positions and render chart layouts with selectable house systems. Chart reports can be output as printable documents and shared via PDF export, which fits practitioners who archive client work. The tool’s fit signals show up in how report settings and chart display options stay tied to a consistent birth profile instead of rebuilding every time.
A tradeoff is that automation is primarily about report creation inside the app rather than programmatic orchestration through an exposed API surface. TimePassages works best when a user or small studio needs repeatable chart reports for many clients, where time spent on consistent settings matters more than integration depth with external systems.
- +PDF chart export supports repeatable client delivery and archiving
- +Birth profile settings keep chart rendering consistent across runs
- +House system and zodiac mode selections cover common practitioner needs
- +Chart wheel and report layout are designed for print-friendly output
- –Limited emphasis on API or external automation for programmatic workflows
- –Aspect grid presentation can feel dense for quick first-pass reviews
- –Birth time rectification workflows are not the primary focus
- –Advanced comparative charts require more manual setup steps

It computes planetary positions and chart placements, supports multiple house-system options, and renders results in chart wheel and table formats for quick review.

Janus
SMBDesktop astrology software for natal charts, transits, progressions, and reports.
Wheel-style chart rendering tied to structured report exports for repeatable client delivery.
Janus focuses on natal chart calculation workflows that start from birth date, time, and location, then generate placement and aspect outputs suitable for reports. Chart configuration supports different house systems, and the results can be rendered into wheel-style visuals and report formats without manual rebuilding.

- +House-system options for practical interpretive variation
- +Export paths that fit client delivery workflows
- –Limited API-centric extensibility versus developer-first tools

How to Choose the Right Astrology Birth Chart Software
We look for differences in how each option calculates and displays a birth chart, then how well it handles your inputs (like birth date/time and location) and exports results. The biggest separator is usually House system handling and Birth time input accuracy.
House system handling options
Why it matters
House system handling changes where life themes land in the chart, so two tools can disagree even when the planet positions look familiar. If you want to compare methods or match what your preferred tradition uses, this matters.
How to check
In the settings, switch between the available house system choices and re-render the same chart. Compare how the house cusps and placements move, and note whether the tool clearly labels what it used.
Zodiac mode and sign display
Why it matters
Zodiac mode affects sign boundaries and can shift interpretations, especially for users following a non-default approach. If you publish or share charts, you need the same visual and label conventions every time.
How to check
Create a chart for a known birthday and toggle the zodiac mode options you see in the demo. Check that the sign labels and any mode wording update consistently across the chart and summaries.
Birth time and place input behavior
Why it matters
Birth time and place input behavior determines whether the chart reflects your actual recorded details or guesses defaults. If your time is approximate, you need to see what the software assumes and how it reports uncertainty.
How to check
Enter a birth time and location, then rerun after changing only one field (time by a small amount or place by city). Also try leaving time blank or marked as unknown if the UI allows it, and see what the output says.
Interpretation panels and chart views
Why it matters
Interpretation depth and chart views determine whether you can read the chart without exporting to another tool. For astrology birth chart software, the value is in how clearly the tool presents placements, angles, and relationships in a consistent layout.
How to check
Open a sample chart and navigate between its main panels (placements list, angles/points area, and relationship or aspects view if present). Verify the labels are readable and that each panel agrees with the displayed chart.
Export formats and sharing outputs
Why it matters
Export formats and sharing outputs matter when you keep a study archive, share charts with clients, or store results in notes. If exports omit key settings (like zodiac mode or house system), you can’t reliably reproduce what you saw.
How to check
Generate an export of a chart and check whether the output includes the chosen settings and the same placements shown on-screen. Compare at least one export type (image and document) to ensure the labels match.
Automation and API surface for charts
Why it matters
Automation and API surface affects whether you can generate charts in a repeatable workflow rather than clicking manually. If you’re building a personal or small-client pipeline, you need predictable inputs and outputs.
How to check
Look for documentation that describes endpoints or scriptable chart generation, and see whether it returns chart data alongside visuals. Ask during the demo how you would supply birth inputs and retrieve settings used for the result.
Red flags
- The chart changes when we switch settings, but exports don’t record which settings were used.
- Birth time and place input fields silently default in ways that aren’t shown in the output.
- House system or zodiac mode options are missing or mislabeled across the on-screen panels.
Fit by situation
- If we use a specific house tradition and switch methods often, prioritize House system handling options.
- If we record uncertain birth times or partial birth details, prioritize Birth time and place input behavior.
- If we need repeatable generation for many charts, prioritize Automation and API surface for charts.
