SiteRemora vs TestParty for Shopify (2026)
Both fix the code rather than covering it. TestParty does it as a service: monthly pull requests, monthly human audits and a certificate, quoted per customer and delivered in weeks. SiteRemora does it as an app: install, scan, approve or automate the fixes, from $79 a month. The choice is service versus self-serve.
What TestParty is
TestParty fixes the source of your site rather than adding a widget, which puts it in the same camp as SiteRemora. The delivery is service-shaped: fixes arrive as monthly GitHub pull requests, a human audit runs monthly, and customers receive compliance certificates. The company raised a $4 million seed round in June 2024, listed a Shopify app in June 2025 with a free listing and services priced by quote, and promises remediation in 14 to 30 days. The listing is rated 5.0 from a couple of dozen reviews. Its writing on overlays is the best in the category.
Side by side
| Aspect | TestParty | SiteRemora |
|---|---|---|
| Approach | Real source fixes, delivered as pull requests. | Edits the theme's Liquid, CSS and HTML and writes alt text into the product record, after a scan of the rendered storefront. The page itself is accessible, with or without JavaScript. |
| Delivery | Monthly pull requests plus a monthly human audit; a sales conversation first. | In the app, from the moment you install; fixes wait for your approval, or run on autopilot if you turn it on. |
| Human audit | Included monthly. | Automated scanning of the rendered store; manual audits are yours to arrange. |
| Certificate | Compliance certificates issued. | A dated scan history and fix log with before and after. No certificate. |
| Time to first fix | 14 to 30 days. | The same day. |
| Undo | Through git. | A revert per change in the app, from the original code kept with each fix. |
| Price | By quote. | Free plan sees every issue; paid plans from $79 a month. |
| Who it suits | Companies that want a team on it and a document at the end. | Merchants without a developer, and agencies maintaining many stores. |
Where TestParty is the better choice
- You want human auditors reviewing the store every month and a certificate to show for it.
- A contract or counsel requires a manual audit, not only automated checks.
- You would rather hand the whole thing to a team than operate a tool.
Where SiteRemora is the better choice
- You want to see where the store stands today, not in a few weeks, and fix it yourself or let the app do it.
- You run a small or mid-sized store and the budget is tens of dollars a month, not a quote.
- You maintain stores for clients and need the same routine across all of them, with a diff and a revert per change.
If you are on TestParty today
There is no conflict between the two; an agency can use TestParty's audits on a flagship store and SiteRemora across the rest. If you move from one to the other, the fixes already in your theme stay there.
Questions people ask
Does either one give a compliance certificate?
TestParty does. SiteRemora gives you a record: dated scans and a fix log with diffs. Neither a certificate nor a record makes a store immune to a claim; both show what was done and when.
Which is faster?
SiteRemora starts scanning when you install it, and fixes can go in the same day. TestParty promises remediation within 14 to 30 days after a sales conversation.
Which is cheaper?
SiteRemora's free plan shows every issue and paid plans start at $79 a month. TestParty's services are priced by quote.
