Our Verdict
Uptime – Automated Store Tests is currently the more compelling choice for most merchants in 2026 due to its established positive reputation (5/5 rating with 30 reviews). Its focus on proactively preventing issues that lead to revenue loss makes it a valuable investment for any store. Justt ‑ Win More Chargebacks, while potentially beneficial for merchants dealing with significant chargeback volumes, lacks any user validation (0/5 rating and 0 reviews). Therefore, merchants should exercise caution and consider alternative chargeback management solutions with proven track records.
Ultimately, the choice depends on the merchant's specific needs. If a store struggles significantly with technical issues and downtime, Uptime is the clear choice. If chargebacks are a major problem and the merchant is willing to take a risk on an unproven app, Justt *might* be worth investigating further, but only after thorough research and perhaps contacting the developers for more information or a trial period.
