SDK Wars FAQ

SDK Wars is a free tool for comparing two SDKs, SDK generators or API client approaches head to head. You pick the two sides and the criteria that matter to you, and it shows who takes each criterion, why, and where to check it, then gives an overall verdict you can share.

Usually a straight answer to "which SDK approach should we use?": hand-written or generated, which generator, or whether an MCP server should sit next to the SDK. Most results for that question are opinion posts or vendor pages. SDK Wars is a working comparison where you set the criteria and every call comes with its reason.

It is free and there is no sign-up. The tool runs in your browser, and the whole matchup (both sides, your criteria, your weights and any ratings you entered) lives in the share link.

Each side gets a level on each criterion you pick: Strong (3 points), Solid (2), Partial (1) or Weak (0). Criteria you mark ×2 count double. A criterion where either side is Not verified is left out of the score and listed, so a gap in what is known never decides the result. If the two totals are within 8% of the maximum, the verdict is Too close to call.

For named tools, each rating is read from the tool's own documentation and links to it, so you can check it. For approaches such as a hand-written SDK or raw HTTP, the rating follows from how the approach works and the reason is written next to it. The Criteria page explains what each level means and how to check it yourself.

Yes. Choose "Your own SDK" on either side, give it a name and rate it on each criterion using the checks on the Criteria page. You can put two of your own SDKs against each other, or your own against one of the listed options.

Use Copy share link to get a link that opens the same matchup, or Copy as Markdown to paste a table of the result, with the link, into a pull request, an issue, a design doc or a chat.

Because SDK Wars could not confirm it from a source. Rather than guess, it leaves that criterion out of the score and links to where you can check. If you confirm it, rate the tool yourself with the "Your own SDK" option.

Not on its own. The score only reflects the criteria and weights you chose. Each worked example also says when each side is the better pick whatever the score, because things like team skills, budget and how unusual your API is rarely fit in a table.

No. Prices and plans change, so SDK Wars doesn't repeat them. Where cost matters to a comparison, it points to the vendor's own pricing page.

Tools ship fast. Every rating for a named tool links to its source; if the source says something different, trust the source. You can always override a rating by comparing with "Your own SDK".

Whether AI agents can call the API as tools through the Model Context Protocol: an MCP server with clear tool definitions, a defined way to authenticate the caller, and calls that can be logged and attributed. The page on SDKs when agents are the caller covers it in full.
