General

Setting	Effect
Reopen the last workspace	Starts in the workspace you used last.
Restore tabs	Reopens your tabs after a restart, with their order and pinned state.
Wrap long lines	Wraps lines in request bodies and the raw response.
Show line numbers	Shows a line-number gutter in editors.
Indent	Uses 2 spaces, 4 spaces, or a tab when formatting JSON and XML.
Interface language	English, Russian, or the system language.
Validate SSL certificates	Rejects HTTPS servers with an invalid certificate. Leave it on: turning it off applies to every workspace.
Trust self-signed certificates for localhost	Accepts self-signed certificates on `localhost`, `127.0.0.1`, and `::1` while validation stays on elsewhere.
Root certificates	Adds a `.pem` CA for a corporate network that intercepts TLS. Remove a CA to stop trusting it.

Appearance

Setting	Effect
Theme	Light, dark, or the system theme.
Accent colour	Blue, purple, green, orange, red, or graphite for buttons, selection, and active tabs.

Requests

Check these values when Schemo and another client get different responses from the same endpoint.

Setting	Effect
Timeout	How long to wait for a response, in seconds. `0` means no limit.
Follow redirects	Follows up to the set number of hops. Turn it off to see a 3xx status and its `Location` header as they came.
Send cookies from the store	Sends cookies saved from earlier responses to the same domain. See Cookies.
HTTP version	Auto negotiates the version. Choose HTTP/1.1 to investigate a server or proxy that behaves differently with HTTP/2.
User-Agent	Sends the application name and version.
Add Accept-Encoding	Asks for gzip and deflate compression.
Show automatic headers	Lists `Host`, `Content-Length`, and other headers the app adds in the request’s Headers.
Keep request history	Keeps history on this device for 7 days, 30 days, or forever.
Clear history now	Shows how much the history takes up and deletes it, bodies included.

Proxy

Mode	Effect
System	Uses `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`. Schemo shows the values it found. They are read at launch, so restart Schemo after you change them.
Manual	Uses the proxy you enter.
Off	Sends every request directly and ignores the environment variables.

For Manual, choose http, https, or socks5 and enter the host and port, or paste a whole address such as http://user@proxy.example.com:3128. Turn on Authentication if the proxy asks for a username and password. Under Bypass, add hosts that should go directly: names, masks such as *.internal, or subnets.

Use Test the connection to open a tunnel through the proxy to a destination you choose. Schemo reports the time it took, or whether the proxy asked for credentials or refused the tunnel.

For a connection that fails before the API responds, follow Diagnose TLS and proxy errors.

The Proxy page in Manual mode with the proxy address, bypass list, and a successful connection test

Browser extension

Install Schemo Bridge for Chrome, Firefox, or Edge, then choose how it captures.

Setting	Effect
Connect automatically	Connects whenever both the browser and Schemo are running.
Remember tabs	Arms capture again on the same addresses after the browser restarts.
Hosts	Every site, or Only the list of hosts such as `api.example.com` or `*.example.com`.
Skip static files	Drops images, fonts, styles, and scripts.
Skip analytics	Drops metrics, pixels, and trackers.
JSON responses only	Keeps only JSON responses.

Filtered requests are dropped in the browser and never reach Schemo.

Updates

Setting	Effect
Check now	Checks for a new version. Release notes shows what changed in the installed version.
Update channel	Stable releases are checked, about once a month. Beta builds come more often and may contain bugs.
Check for updates automatically	Checks in the background and shows when it last checked.
Download in the background	Downloads an update so Update and restart installs it at once.

When an update is available, the status bar and the update window offer Update and restart, Remind me later, and Skip this version. Schemo verifies the update’s signature before installing it.
