Work starts as a request, not a blank ticket

Most issue trackers assume defects arrive fully structured. OpusMarker is engineered for the messy real world: in-context customer bug reports routed directly into a disciplined pipeline.

Capture

Capture in live context

Clients and teammates report bugs directly from your live application using our lightweight script — capturing exact screen crops, URL, device, and browser state automatically.

dd_widget.open({ tags: ['Checkout', 'UI'] })
Triage

Triage with dual ownership

Every ticket is routed through custom project stages with dedicated Fixer and Tester assignments, preventing ambiguity about who writes the code and who verifies it.

Assigned: Fixer (David) • Tester (Maria QA)
Verification

Verify against original proof

Tasks cannot be closed until the assigned tester inspects the resolution against the original visual evidence, eliminating regression ping-pong.

Status: Ready for Retest → Verified Fixed

Everything required to resolve software defects

A complete suite for fast-moving engineering teams, QA departments, and external client collaborators.

Sprint & Backlog Velocity

Visual Kanban boards with instant list density

Switch between high-level visual lanes and a dense keyboard-friendly list with instant multi-facet filtering by assignee, priority, status, or tag.

Active Filter: Priority = CriticalShowing 6 of 24 tasks
Zero-Collision Widget

Single script embed in Shadow DOM

Runs on any client site without CSS collisions. Captures area screen crops, annotations, and metadata in one tap.

Role Isolation

Zero-cost external client access

Invite clients and external QA testers to submit and review tasks without burning team seats or exposing internal company settings.

CLClient Guest (Project-Scoped Access)
Two-Party Verification

Dedicated Fixers & Dedicated Testers

No task is marked resolved by the person who wrote the code. The assigned tester must verify against original proof before closing.

Stop juggling four disconnected tools to track one bug

Generic project boards lose customer context. Disconnected screenshot tools leave developers guessing. Here is what changes when you consolidate:

Without OpusMarker
  • Bug reports arrive as fuzzy screenshots pasted into Slack or WhatsApp
  • Tasks live in one tool, customer feedback in another with zero traceability
  • "Who's fixing this?" requires endless hallway ping-pong and status meetings
  • External clients are forced to pay for full enterprise seats just to review progress
With OpusMarker
  • Clients submit issues via embeddable widget with instant area snips and metadata
  • One unified workspace for internal engineering tasks and external client feedback
  • Explicit Fixer, Tester, and Assignee roles for every single workflow transition
  • Zero-cost external guest access: clients view and comment only on their project
