Scalar plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Open source renderer | Free | 5 | Entry tier |

What the product covers
The full Scalar feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.
Other
- OpenAPI driven reference
- Embedded API client
- Generated code samples
- Framework adapters
- Themeable renderer
- Self hostable
- Spec validation
People bring Scalar in for replacing default swagger ui on a public api without moving to a hosted documentation vendor, a framework that already emits an openapi document and needs a reference page mounted on a route, an internal api portal that must run inside a private network with no external calls, a team that wants readers to make authenticated test calls without leaving the reference page. If that is not the job you are buying for, the alternatives to Scalar are worth a look before you commit to a tier.
How that compares in Documentation
Too few documentation tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.
| Tool | Entry price | Model | Rated | Head to head |
|---|---|---|---|---|
| Scalar (this page) | Free | Open source, no licence fee | - | |
| Paligo | On request | Per author seat per year | - | vs Scalar |
| Guidde | Free, then $19/month | Per creator per month | - | vs Scalar |
| Adobe RoboHelp | On request | Per user per month, annual commitment | - | vs Scalar |
| HelpDocs | On request | Per editor seat per month | - | vs Scalar |
| MadCap Flare | On request | Per author per year, annual subscription only | - | vs Scalar |
| Doxygen | Free | Open source, no licence fee | - | vs Scalar |
Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the Scalar badges page.
Before you pay for Scalar
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: a single tier at Free. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
Scalar runs on web, macos, windows, linux, and is published by Scalar of Remote, Worldwide. The full record is on the Scalar review, and the rest of the category is under best documentation tools.
