Gr4vy and Omno are both payment orchestration platforms, with different starting points. Gr4vy starts from infrastructure: each merchant gets its own cloud instance, a drop-in checkout and SDKs, a vault, and Flow rules that decide how each transaction is routed, declined or authenticated. Omno starts from the checkout: a hosted session in which customers pay and receive payouts by card, local method or crypto, with routing rules the merchant sets around each customer.
Where Gr4vy is stronger
Dedicated instance per merchant. Gr4vy’s platform page describes a single-tenant cloud instance for each merchant, scalable across regions, with data kept in-region and automatic failover and redundancy. For merchants with data residency or isolation requirements, that is a clear advantage.
Documented routing and retries. Gr4vy’s Flow documentation lists 23 conditions for card transactions, from amount and BIN range to card country, scheme, metadata, product categories and the anti-fraud decision, with decline, route and 3DS actions. It also publishes which ISO decline codes retry on the next connection and which stop the cascade. Few vendors document this so openly.
Tokens beyond the vault. Gr4vy provisions network tokens for stored cards and offers an account updater that refreshes expiry dates and other card details. Omno offers tokenization and saved cards but does not state network token or account updater support on its site.
SDKs and public docs. Embed drop-in checkout for web, SDKs for React, iOS, Android and React Native, Secure Fields for a custom form, and server SDKs in C#, Go, Java, PHP, Python and TypeScript, all publicly documented. Omno’s hosted checkout opens with a Web SDK or in an iFrame, and Card Fields put three secure card fields in your own checkout.
Named references. Gr4vy’s homepage names customers such as Grammarly, Trek, JustGiving and Zip. Omno does not publish client names.
Where Omno is stronger
Payouts in the checkout, to more instruments. Omno’s hosted checkout can open the payout view in the same session as the payment view, and Pay-Out sends customer payouts, seller payouts and cashback to cards, local methods and crypto. Gr4vy’s payouts guide says payouts are currently card OCT only, through PSPs that support them.
Crypto in the same session. Omno shows crypto next to cards and APMs. Gr4vy’s connections list includes one crypto connection, aimed at nonprofit fundraising.
Verification level as a named input. Omno’s eligibility rules take customer groups and customer verification levels (KYC groups and levels in the API) as named inputs. On Gr4vy the same outcome would need metadata conditions that your integration fills.
Local depth in every market. Omno serves e-commerce merchants in every country except markets under OFAC sanctions or on the FATF call-for-action list, with country guides on the local methods that matter in markets such as Kazakhstan, Saudi Arabia and Brazil.
Pricing and commercial model
Neither vendor publishes prices. Gr4vy’s site has an ROI calculator; Omno’s pricing is available on request. Ask for quotes in the same structure: platform or instance fee, per-transaction fee, whether retried attempts are billed, payout pricing and exit terms.
Who should choose which
Choose Gr4vy if:
- Single tenancy or in-region data storage is a requirement.
- You want to read the full routing and retry logic in public documentation before you buy.
- Native mobile SDKs, network tokens and account updater are on your list.
Choose Omno if:
- You want one hosted checkout for payments, payouts and crypto.
- Payouts must reach local methods and crypto, not only cards.
- Customer verification level and customer group should decide which providers a customer can use.
- You sell in many markets and need the local methods of each, such as Kaspi in Kazakhstan, mada in Saudi Arabia or PIX in Brazil.
How we compared
Omno publishes this page, so we have a commercial interest. Every Gr4vy cell links to Gr4vy’s website or public documentation as it read on 19 October 2026. Where Gr4vy is silent we write “Not published”, which does not mean the feature is missing. Omno is described by capability only, from its own product and developer pages. If you work at Gr4vy and see an error, contact us and we will correct it.
