OpenAny.

What it is

OpenAny is a free VS Code extension that opens and inspects HAR files — the network-capture files browsers export when someone asks you to "attach a HAR" to a support ticket. A one-time Pro license adds one-click redaction, diffing two captures, and exporting a request as curl, fetch, or Playwright code. It's the first of a planned family of viewers for files VS Code doesn't handle well on its own.

Who it's for

A support engineer, backend developer, or anyone who gets asked to paste a HAR file into a bug report and doesn't want to hand over live session cookies and bearer tokens by accident.

Why I built it

The two HAR viewers already on the VS Code Marketplace hadn't been updated since 2022 and 2023, and neither redacts anything. HAR files carry live session cookies and auth tokens — that's exactly the kind of data that leaked in the 2023 Okta breach, via HAR files uploaded to support cases. VS Code's own AWS and browser-vendor toolkits don't touch HAR files at all, so it was a real gap, not a crowded one.

How it works

Everything runs locally in the editor: the extension parses the HAR file on your machine, and nothing about the file itself is ever sent anywhere. Free tier gets you the waterfall view, headers, and bodies. Pro unlocks redaction (strip cookies and tokens before you share a file), diffing two captures against each other, and exporting any request as ready-to-run curl, fetch, or Playwright code. The only thing that ever talks to a server is a one-time license key check against Polar — the extension collects no telemetry and phones home to nothing else.

What's next

Two more viewers are planned under the same Pro license: an email (.eml/.msg) viewer with SPF/DKIM/DMARC header analysis, and a streaming viewer for multi-gigabyte JSONL and log files.
