How much does it cost to build an app like Linear?

There is no one figure, because "an app like Linear" covers three very different builds: a first version with only the essential features, a complete and credible competitor, and a rebuild of everything the mature product does at the traffic it carries. Those are several-fold apart. What this page gives you is the shape of each — the sides, the feature tiers, the stack and the compliance — and the calculator turns whichever one you actually mean into a cost range, hours and a timeline.

Because it is not one app. It is 3 separate applications — team client, workspace administration, developer integrations — sharing one backend, each with its own design, release cycle and test matrix. Most quotes that come in low have counted one of them. Local-first sync is the architecture: Holding a synchronised client-side dataset buys instant interaction and costs you offline mutation queues, conflict resolution, cache schema migrations and permission-scoped partial sync. It is a deliberate, expensive trade.

Yes, and you should. A first version ships the essential feature tier rather than all three, on fewer surfaces, at a launch-sized audience — materially less than the full product, and the calculator will show you by how much. What it does not cut is compliance: technology & saas obligations apply from the first user, so those stay in whatever else is deferred.

It depends on the same three things the cost does — which tier of the product you mean, how many surfaces you ship, and how settled the scope is. The calculator returns a timeline alongside the cost, derived the same way: hours divided across a realistic team shape, never a target date worked backwards from.

Cloud infrastructure, third-party services and annual maintenance, and the calculator reports all three separately from the build. They are kept out of the build figure deliberately: they are operating expenditure rather than capital, and adding the two together produces a number that means nothing. Maintenance in particular is not optional — an app that receives none stops working within about a year as OS releases and SDK deprecations accumulate.

This page carries no figures at all, and nobody outside the company has real ones. What it describes is the product SHAPE, observed from what any user can see — the sides, the feature tiers, the stack, the compliance. Nothing here describes what Linear actually spent, earns, employs or runs on. The calculator prices building something of that shape today, for the United States market, at our own blended delivery rate.

Typically $30,000–$70,000 over the equivalent single-tenant product, and considerably more if you retrofit it. The cost is not a tenant column on your tables — it is that every query, cache key, background job, export and test must be tenant-aware, and that a single missed filter is a data breach rather than a bug. That raises your security and QA bar permanently. Design for it from the start even if you launch with one customer.

When a deal depends on it, not before — but design so you can. SAML SSO, SCIM provisioning, audit logs and role granularity total $80,000–$180,000 of engineering, and SOC 2 Type II adds $20,000–$45,000 in auditor fees on top of the evidence work. Building it speculatively is premature. Building your auth layer and data model so it can be added without a rewrite costs almost nothing and saves a painful quarter later.
