Chargeblast vs Justt: What Each Vendor Says
A side-by-side read of what Chargeblast says it does and what Justt says it does. Each vendor's claims in its own words, with no winner named.
Two chargeback tools come up in the same search. One is built around alerts. The other calls itself an AI platform. This page puts Chargeblast and Justt side by side, using only what each vendor says about itself.
What Chargeblast says it offers
Chargeblast's docs say it offers three types of alerts: Ethoca, CDRN and RDR. Each one works differently, and Chargeblast describes who does the refunding in each case.
Chargeblast's docs say Ethoca is a Mastercard service that covers both Mastercard and Visa transactions. Chargeblast's docs say Ethoca alerts require merchant-side refunding. So when an Ethoca alert arrives, the merchant is the one who acts on it.
Chargeblast's docs say CDRN is an issuer based product offered by Visa. Chargeblast's docs say RDR is a dispute resolution product offered by Visa where the acquirer is responsible for refunding the transactions. Chargeblast's docs say no action is required by the merchant for RDR.
So the three alerts split by who refunds. Ethoca puts it on the merchant. RDR puts it on the acquirer. Chargeblast's docs call CDRN an issuer based product.
What Justt says it offers
Justt's site describes its platform as AI-native, enterprise-grade chargeback management. Justt says it uses advanced AI technology to deliver customized, automated solutions for merchants.
Justt's site lists platform, alerts, insights, integrations, and Justt for Shopify among its offerings. Justt integrates across your payment stack and unifies every chargeback into a single, live dashboard.
The alerts piece overlaps with what Chargeblast sells. Justt's site says it integrates Ethoca and Verifi alerts directly, with automated refund decisions you configure. So Justt names Ethoca, which Chargeblast also names, and adds Verifi.
Justt's site also describes Dynamic Arguments. Justt's site says Dynamic Arguments builds unique, evidence-backed proof for every dispute automatically.
Alerts and automated refunds compared
Both vendors sell alerts, and both name Ethoca. The difference is in what each says happens after the alert.
Chargeblast's docs describe the alert chain and who refunds in it. The merchant handles Ethoca refunds. The acquirer handles RDR refunds.
Justt's site says its alert integrations come with automated refund decisions you configure. So Justt describes a rules layer on top of the alerts, where the merchant sets the policy and Justt applies it.
They describe different pieces of the same problem.
Dispute prevention and pre-dispute resolution
Justt's site says Order Insight and Consumer Clarity resolve cardholder confusion before a dispute is ever filed. That is a prevention claim, aimed at the moment before a customer calls their bank.
Justt's page says PayPal, Klarna, and other alternative payment methods let you resolve disputes with customers before they become chargebacks. So Justt describes prevention work outside the card networks too.
Evidence and dispute representation
Justt's site says it tailors evidence and arguments to the chargeback patterns of your vertical.
Justt's site says repeat disputers are detected using cross-merchant network data. That is a claim about spotting customers who dispute often, using data from beyond one merchant.
Justt's site says Dynamic Arguments builds unique, evidence-backed proof for every dispute automatically. Put together, Justt describes a system that writes the evidence, shapes it to the vertical, and flags repeat disputers along the way.
Coverage across payment methods and markets
Justt's page says it can automatically issue refunds on Apple Pay and Google Pay disputes based on your policies. Justt's page says PayPal, Klarna, and other alternative payment methods let you resolve disputes with customers before they become chargebacks.
So Justt names Apple Pay, Google Pay, PayPal and Klarna in its own words. Justt also says it integrates across your payment stack.
Chargeblast's docs name three alert types: Ethoca, CDRN and RDR.
Security and compliance
Justt says it holds SOC 2 Type II and full ISO 27001-family certifications. Justt's page says customer data is segregated and encrypted in transit and at rest.
How to choose between them
This section frames the choice using what each vendor says.
Ask what problem comes first. If the need is alert coverage and knowing who refunds in each chain, Chargeblast's docs describe exactly that, across Ethoca, CDRN and RDR. If the need is automated evidence built per dispute, Justt says it does that with Dynamic Arguments and vertical-tailored proof.
Ask where the disputes come from. Justt names Apple Pay, Google Pay, PayPal and Klarna in its own words. Chargeblast's docs name Ethoca, CDRN and RDR.
Ask who acts on an alert. Chargeblast's docs say Ethoca needs merchant-side refunding and RDR needs none. Justt says its alert refunds run on policies you configure.
Ask what must be proven to a security reviewer. Justt states its certifications.
Then go to each vendor's own site for pricing, contracts and anything neither states.
Where to go next

Two more comparisons on this site cover Chargeblast against other tools. One is chargeblast vs chargeback.io. The other is chargeback gurus vs chargeblast. Each follows the same rule as this page: what each vendor says, in its own words.
