Mergiato vs gh-dash

The short answer

• Pick gh-dash if you live in the terminal, want PRs and issues in sections you define yourself, and like to script your own commands.
• Pick Mergiato if you want to read and comment on the diff itself, see each CI job, follow stacks, and merge through your repo's queue, in one window.

Side by side

	gh-dash	Mergiato
Where it runs	In your terminal, as a gh extension	A desktop app
Sign-in	Your gh sign-in	Your gh sign-in
Lists	PRs and issues, in sections you write as GitHub searches in a YAML file	Your PRs and the reviews waiting on you, ready out of the box; PRs only
Reading the diff	In your pager (less by default, or a tool like delta)	In the app: unified or split, syntax colors, up to 3,000 files, Viewed marks
Commenting	A comment on the PR	Comments on a line or range, replies, reactions, resolve
Checks	Watch a PR's checks and get a notification when they finish	Each job's state and time; re-run failed jobs, all, or one
Stacks and merge queues	Not listed in its docs; merge runs gh pr merge	Graphite, GitHub and branch-chain stacks; Graphite's and GitHub's merge queues
Customizing	Keybindings, sections and your own commands, all in config	Settings, themes and layout choices; no custom commands
Price	Free, open source (MIT)	Free while in beta
Runs on	Wherever the GitHub CLI runs	macOS today; more platforms are coming

Where gh-dash is the better pick

• You'd rather never leave the terminal, or you work over SSH.
• You track issues next to PRs, in sections tuned to your own searches.
• You want to bind your own commands, like opening lazygit on the PR's branch.
• You want something open source you can change.

Where Mergiato is the better pick

• You review big diffs and want to comment on the exact line, with every file in view. How it handles large PRs.
• You fix red builds from the PR: each job, timed, re-run in one click.
• Your team stacks PRs and merges through a queue: stacks in Mergiato.
• You want it working the moment it opens, with nothing to configure.

Using both

They share the same gh sign-in, so there's nothing to set up twice. Keep gh-dash for a quick look from the terminal, and open the PR in Mergiato when it's time to read the diff and merge.
