Orbit vs Karix — frequently asked
- Is Orbit a good Karix alternative?
- Orbit is the AI-first alternative to Karix. Karix is the India-first enterprise SMS platform — SMS, OTP, and WhatsApp Business behind a sales-assisted posture. Orbit is the AI-first alternative: the same regional SMS footprint plus AI voice agents, RCS, email, video, and a native customer data platform behind one self-serve, pay-as-you-go bill. You get AI voice agents plus every other channel on one platform and one pay-as-you-go bill, with self-serve signup and no annual contract minimum.
- What does Orbit offer that Karix doesn't?
- Karix is the India-first enterprise SMS platform — SMS, OTP, and WhatsApp Business behind a sales-assisted posture. Orbit is the AI-first alternative: the same regional SMS footprint plus AI voice agents, RCS, email, video, and a native customer data platform behind one self-serve, pay-as-you-go bill. Orbit runs AI voice agents, SMS and MMS, WhatsApp, email, embeddable video, and a built-in contact center on a single platform with one unified bill, instead of separate products you integrate and reconcile yourself.
- How does Orbit's pricing compare to Karix?
- Orbit is pay-as-you-go with pricing published on the website, self-serve signup, and no annual contract minimum. Every channel is billed on one account, so you get a single invoice across voice, messaging, email, and video instead of a separate bill per product — and the rate you see is the whole cost: no per-product fees, no carrier or compliance surcharges, and no paid support tier stacked on top of usage.
- Can I run AI voice agents on Orbit instead of Karix?
- Yes. AI voice agents are a core part of Orbit, not an add-on layer, and they run alongside programmable voice, SMS, WhatsApp, email, and video on the same platform — so you are not stitching an AI-agent product onto Karix's API stack yourself.
