Mainline

Mainline vs Jira

Does your team practice CI and CD? YES Is WIP limited to one story per person? YES Do you break work into thin, testable slices? YES Do you separate deploy from release? YES Do you estimate with story points? NO NO NO NO NO YES Use Jira. Try Mainline.

Mainline and Jira are both project management tools that engineering teams use, and that's where the similarity ends.

Jira was designed to be a configurable workflow engine. It can model Scrum, SAFe, Kanban, waterfall, or ITIL change management. It will implement whatever process its administrators ask for, including processes that harm the teams using them. Frederick Taylor would have loved Jira: decompose work into measurable units, assign each unit to a worker, measure the workers.

Mainline is built for one way of working: trunk-based development, continuous integration, continuous delivery, explicit collaboration modes, no individual metrics. There is no configuration mode where it becomes a Jira clone. The shape of the tool is the shape of the practice.

If your team follows these practices, or wants to, Mainline is sharper. If you need arbitrary workflows, configurable approval chains, or ITIL ceremonies, Jira is the right tool. We are not in the same category.

Mainline Jira
Primary unit of work User story on a story map Ticket in a workflow
Estimation model Lead-time distributions from your team's actual history Story points, t-shirt sizes, custom fields
Backlog None. A backlog is a landfill. First-class concept
People per story As many as are working on it. Solo, pair, or ensemble. One assignee. You cannot put a second person on a card.
What "done" means Released to users Configurable, usually a workflow column
Deploy / release lifecycle Deploy and release are separate events. A story cannot be released until it has been deployed. No native distinction. Can be modelled via custom workflow columns.
Who can see what Every view is the same view, including the manager's Per-role permissions, manager-specific reports
Per-developer metrics None. Surveillance is not a feature. Available via Atlassian Analytics and third-party add-ons
WIP enforcement One active story per person - enforced as a database-level unique constraint, not a soft limit Suggested via WIP limits in board settings
Pricing model Flat. Free for one person. $99 / 8 people. $179 / 16 people. Per seat. $7-$15 / user / month, gates above 10 users.
What happens if your team grows past the price band Start a second Mainline Per-seat cost grows with headcount
Data export Full JSON export including complete event history Atlassian migration tools - project-by-project, configuration is not fully portable
Audit trail / event log History cannot be edited - append-only events, enforced by database triggers. Every view is computed from the log, and even AI reads are in it. Change history at the application layer. Comments and descriptions stay editable after the fact.
Worldview encoded in the data model Continuous flow with paired delivery - the practices DORA associates with elite performers Configurable; wraps around whatever dysfunction and broken process your team operates in

When to choose Mainline

Your team is between 2 and 16 engineers. You practice trunk-based development, or you want to. You ship continuously, or you want to. You are tired of arguing about story points. You believe per-developer metrics do more harm than good. You want flat pricing.

When to choose Jira

Your engineering org is large enough that no single tool's worldview will fit, so you buy configurability instead of an opinion. You employ a Jira administrator to operate the tool that was supposed to help you ship. You need the Atlassian ecosystem (Confluence, Bitbucket, Jira Service Management). You need approval workflows, custom fields, or per-ticket discussion threads; Mainline doesn't have these. For those situations, Jira is the right answer. Mainline is for teams who have - or want - engineering practices beyond ticket processing.

We also have comparisons against Linear and Asana. If you'd like to see Mainline compared to a tool we haven't covered, email us.
