DarnlyIf you're looking for a Jam alternative because you build alone with Claude Code, Codex or Cursor, this page is for you. Both tools turn "this is broken" into a report with the technical details a developer, or an agent, needs. They're built for different moments. Here's an honest look, with Jam's facts taken from its own pages on 8 November 2026.
The short version
- Pick Jam if you need to show a bug as a video, your team, QA or support sends you bugs, customers should be able to record one from a link, or your work lives in Jira, Linear or Slack.
- Pick Darnly if you're the one finding the bugs, you want each one saved in your project with no account, and you want your agent to work through the list and check each fix.
Side by side
| Darnly | Jam | |
|---|---|---|
| Made for | People building with AI coding agents, reporting their own bugs | Software teams, QA, engineering and support |
| Price | Free, no monthly limit on bugs | Free plan (30 Jams and 5 Recording Links a month, 5-minute recordings). Team is $14 per creator a month, billed yearly. |
| How you capture | One key, click the broken element, type what you expected | Screen recording or screenshot from the Chrome extension, plus instant replay |
| What the report holds | Marked screenshot, the element (selector, HTML, styles), the file that drew it on a local project, your note, errors and requests from the last 60 seconds, the steps that led to the bug, and the shape of the data behind the element | Video or screenshot, console logs, network requests, user events, device details, and an AI title, summary and repro steps |
| Video | No | Yes, that's the core of Jam |
| Where reports go | Files in your project's .darnly/inbox/, your clipboard, or an optional private cloud inbox | A Jam link in your Jam workspace, and integrations like Linear, Jira and Slack |
| AI coding agents | Adds AGENTS.md and a skill so Claude Code, Codex or Cursor read the inbox with no connector. Optional MCP at api.darnly.dev/mcp | Jam MCP at mcp.jam.dev/mcp, with setup for Claude Code, Cursor, Codex and more |
| After the fix | Each report tells the agent how to check its own fix in a browser, then it marks the bug fixed | Agents can read Jams and comments. Jam CLI lets agents publish videos as Jams to show their work. |
| Account needed | No, unless you use the cloud inbox | Yes, Jams live in a Jam workspace and Jam MCP signs you in |
| Beyond the browser | Mac app for Mac apps, iOS Simulator and Android Emulator | Jam for Mac and Jam for iOS |
Where Jam is the better pick
Jam is a mature tool for teams, and some bugs really need what it does.
- Bugs that need a video. An animation that stutters, a flow that breaks on step four, a bug you can't explain in a sentence. Jam records it, and its MCP lets an agent read the transcript and frames.
- Bugs from other people. Recording Links let anyone record a Jam with nothing to install, and Jam for Fin lets customers record one inside an Intercom chat. Darnly needs the reporter to install the extension.
- Team tools. Jam sends bugs to Linear, Jira or Slack and has webhooks. Darnly doesn't integrate with trackers.
- Company needs. Jam lists SOC 2 Type II, SSO, audit logs and admin controls.
Where Darnly is the better pick
- Bugs go straight into your code folder. Each one is a markdown file and a PNG in
.darnly/inbox/, next to your code and kept out of git. Type/darnlyor say "fix my Darnly bugs", and your agent works through them, with no link to open and nothing to sign in to. - It points at the exact thing. You click the broken element, so the report names it, and you can say "Change only this one" or "Change all like it". That answers the agent's usual "just this button, or every button?" before it asks.
- The agent checks its own work. Each report says how to check the fix in a browser, and the agent marks the bug fixed when it's done, so your list empties as you go.
- No monthly limit. Capture as many bugs as you find in a testing session. Jam's free plan allows 30 Jams a month.
- Private by default. No account, and nothing is sent to Darnly unless you turn on the cloud inbox. Passwords, card numbers, tokens and keys are hidden before saving, and Darnly never keeps what you type or the values in your data.
Using them together
They fit different moments. Use Jam when a teammate or customer needs to show you something, or a bug only makes sense as a recording. Use Darnly for the stream of small things you notice while you test your own app: this button, that gap, this error. If testers send you bugs by email or chat instead, the guide on sending bugs from a tester or client to your AI agent shows a free way to do it. For a team feedback widget, see Darnly vs Marker.io.
