The 6 best in-app feedback widgets in 2026
An in-app widget catches feedback at the moment of frustration, with the screenshot, console log, and browser context a written report always omits. The tools in this category look alike in the demo — a floating button, an annotation layer — but they split cleanly by audience: widgets built for your customers, and widgets built for your own QA and design reviewers.
We build Modem, one of the entries below. Modem is not a widget, so we've placed it last as a different approach; judge the rest of the ranking with that disclosure in mind.
“export is broken for us”
“any update on SSO?”
“we hit the rate limit again”
Read + clusteredThe short version
| Tool | Built for | Feedback lands in |
|---|---|---|
| Gleap | Customers (web + mobile) | Its own support/feedback platform |
| Marker.io | Internal QA and clients | Jira, GitHub, ClickUp, Trello |
| Userback | Customers and clients on web | Its dashboard or project tools |
| Usersnap | Customers, with surveys | Its dashboard or integrations |
| Feedbucket | Agencies and site reviewers | Project tools |
| Modem | — | No widget; captures from existing channels |
1. Gleap
Gleap is the most complete customer-facing option: bug reporting, support, AI answers, feedback, and roadmap updates in one platform, with SDKs for web and mobile. Reports arrive with replay-style context, and Gleap can notify the reporter when the bug is fixed — the widget-scale version of closing the loop.
The trade-off is platform gravity: the widget works best when you also adopt Gleap's support inbox and feedback surfaces.
Where it fits: SaaS and mobile teams that want reporting, support, and feedback consolidated in one vendor.
2. Marker.io
Marker.io is the internal-QA specialist: annotated screenshots from a website flow straight into Jira, GitHub Issues, ClickUp, Trello, and similar trackers, which makes it the natural pick for QA rounds and agency review cycles. It is deliberately not a customer support platform — no support inbox, no roadmap loop.
Where it fits: teams whose "users" are testers, clients, and designers filing into a tracker the team already lives in.
3. Userback
Userback focuses on visual web feedback: users annotate screenshots, record video feedback, and submit issues that teams manage from a dashboard or push into project tools. It leans more SaaS-product than Marker.io, with feature-request and roadmap features attached, though it's thinner if you need mobile SDKs or a full support inbox.
Where it fits: web products that want customer-facing visual feedback without adopting a whole support platform.
4. Usersnap
Usersnap pairs the annotation widget with in-app surveys and feedback forms, aiming at product teams that want to solicit feedback, not just receive it. It sits between Marker.io's QA focus and Gleap's platform ambitions, and shows up as the incumbent in most category comparisons.
Where it fits: product teams that want bug capture and micro-surveys from one widget.
5. Feedbucket
Feedbucket targets the agency and website-review use case: a lightweight script, screenshot annotation, and feedback routed to project tools, competing on simplicity against heavier incumbents.
Where it fits: agencies collecting change requests on client sites without asking clients to learn a tool.
6. Modem — a different approach
Modem has no widget to install, and if in-the-page annotation is the requirement, use one of the five above. Modem starts from a different observation: for most B2B products, the highest-signal feedback never touches a widget — it's said in a shared Slack channel, a support ticket, or a sales call.
Modem captures from those channels automatically, then does the after-capture work widgets leave to you: deduplicating and aggregating reports into quantified issues, routing them into your tracker, and notifying reporters when the fix ships. Widget reports can join that stream too — several widget tools above push into GitHub or Jira, where Modem picks them up. The merging happens in one context graph of topics, reporters, and companies, so a widget report and a Slack complaint about the same bug read as one issue, not two.
Where it fits: B2B teams whose feedback lives in conversations. Where it doesn't: prosumer and consumer apps with no shared channels, where a widget is genuinely your only capture surface.
How to choose
Decide who is holding the mouse. Internal QA and client reviews: Marker.io or Feedbucket, into the tracker you already use. Customer reporting on a web app: Userback or Usersnap. Customer reporting where you also want support and loop-closing handled: Gleap. Then look at what happens to reports after capture — a widget solves the first ten seconds of feedback handling, and the pile-up happens afterward, in triage. If reports from the widget land next to reports from Slack and support with nobody merging them, that's the aggregation problem, and it's a different tool category.
