Choose Jira if you run software like a program
Jira Software is the default for backlog, sprints, and custom workflows. The Free plan covers up to 10 users. Paid Standard starts around $8 per user per month. Jira is not a customer help desk. For that, Atlassian sells Jira Service Management as a second product, billed per agent. A five-person shop that wants both bugs and customer tickets usually ends up paying for two Atlassian seats stacks, plus time spent configuring them.
Pick Jira if your team already lives there, or if you need marketplace apps, advanced boards, and enterprise workflow. Pick PatchDesk if you want a ticket list and a customer inbox this afternoon without standing up JSM.
Choose Zendesk if support is the company
Zendesk is a customer-service platform. Support Team starts at $19 per agent per month for email-style ticketing. The Suite most teams actually buy starts at $55 per agent per month and adds messaging, phone, and a help center. There is no free forever plan. Zendesk does not replace an engineering issue tracker.
Pick Zendesk if you staff a support org and need channels beyond a web form and email. Pick PatchDesk if a small team answers customers and files bugs, and you do not want a $55-per-seat desk plus Linear or Jira on the side.
Choose Linear if engineering is the only customer
Linear is a fast issue tracker. The Free plan is real, with caps (a couple of teams and a few hundred issues). Basic is $10 per user per month on annual billing. It is excellent at cycles, keyboard-driven triage, and GitHub-shaped work. It is not a customer support desk. Linear Asks exists on higher plans for intake; it is not a branded “no account required” portal with SLA and macros.
Pick Linear if you only track engineering work and already have another place for customers. Pick PatchDesk if a support email has to become a bug without leaving the product.
Choose PatchDesk if you need both, cheaply
PatchDesk is $7 per active user per month. One plan includes unlimited issues, unlimited support tickets, a public customer portal, SLA, macros, MFA, roles, and CSV import/export. A 14-day trial does not require a card.
You give up Linear’s polish, Jira’s workflow engine, and Zendesk’s omnichannel suite. Help articles live in the knowledge base. There is no phone or live chat. If that list does not describe your next six months, the simpler desk is the point.
