A powerful HTTP client that lives in your terminal.
Posting is an HTTP client, not unlike Postman and Insomnia. As a TUI application, it can be used over SSH and enables efficient keyboard-centric workflows. Your requests are stored locally in simple YAML files, meaning they're easy to read and version control.

Some notable features include: "jump mode" navigation, environments/variables system with autocompletion, syntax highlighting powered by tree-sitter, Vim keys, various builtin themes, a configuration system, "open in $EDITOR", and a command palette for quickly accessing functionality.
Posting was built with Textual.
Posting can be installed via pipx
:
pipx install posting
Python 3.11 or later is required.
More installation methods (brew
, etc) will be added soon.
Requests are stored directly on your file system as simple YAML files, suffixed with .posting.yaml
- easy to read, understand, and version control!
Here's what they look like:
name: Create user
description: Adds a new user to the system.
method: POST
url: https://jsonplaceholder.typicode.com/users
body:
content: |-
{
"firstName": "John",
"email": "[email protected]"
}
headers:
- name: Content-Type
value: application/json
params:
- name: sendWelcomeEmail
value: 'true'
To open a collection (a directory containing requests), use the --collection
option:
posting --collection path/to/collection
This will recursively find and display requests in the sidebar.
If you don't supply a directory, Posting will use the default collection directory.
You can check where this is by running posting locate collection
.
Posting can be navigated using either mouse or keyboard.
Jump mode is the fastest way to get around.
Press ctrl+o to enter jump mode.
A key overlay will appear on the screen, allowing you to jump to any widget by pressing the corresponding key.
tab and shift+tab will move focus between widgets, and j/k/up/down will move around within a widget.
Where it makes sense, up and down will move between widgets.
Many widgets have additional bindings beyond those displayed in the footer. You can view the full list of keybindings for the currently focused widget, as well as additional usage information and tips, by pressing f1 or ctrl+? (or ctrl+shift+/).

Press ctrl+c to quit Posting.
You can use variables in the UI using the ${VARIABLE_NAME}
or $VARIABLE_NAME
syntax.
These variables will be substituted into outgoing requests.
.env
files can be loaded using the --env
option.
Variables from these files can then be used in the UI.
Imagine you're testing an API which exists in both dev
and prod
environments.
The dev
and prod
environments share some common variables, but differ in many ways too.
We can model this by having a single shared.env
file which contains variables which are shared between environments, and then a dev.env
and prod.env
file which contain environment specific variables.
# file: shared.env
API_PATH="/api/v1"
ENV_NAME="shared"
# file: dev.env
API_KEY="dev-api-key"
ENV_NAME="dev"
BASE_URL="https://${ENV_NAME}.example.com"
# file: prod.env
API_KEY="prod-api-key"
ENV_NAME="prod"
BASE_URL="https://${ENV_NAME}.example.com"
When working in the dev
environment, you can then load all of the shared variables and all of the development environment specific variables using the --env
option:
posting --env shared.env --env dev.env
This will load all of the shared variables from shared.env
, and then load the variables from dev.env
. Since ENV_NAME
appears in both files, the value from the dev.env
file will be used since that was the last one specified.
Note that you do not need to restart to load changes made to these files, so you can open and edit your env files in an editor of your choice alongside Posting. However, autocompletion and variable highlighting will not update until Posting is restarted.
If you want to permit using environment variables that exist on the host machine (i.e. those which are not defined in any .env
files), you must set the use_host_environment
config option to true
(or set the environment variable POSTING_USE_HOST_ENVIRONMENT=true
).
Since all Posting configuration options can also be specified as environment variables, we can also put environment specific config inside .env
files. There's a dedicated "Configuration" section in this document which covers this in more detail.
For example, if you wanted to use a light theme in the prod environment (as a subtle reminder that you're in production!), you could set the environment variable POSTING_THEME=solarized-light
inside the prod.env
file.
Note that configuration files take precedence over environment variables, so if you set a value in both a .env
file and a config.yaml
, the value from the config.yaml
file will be used.
Some functionality in Posting doesn't warrant a dedicated keyboard shortcut (for example, switching to a specific theme), and can instead be accessed via the command palette.
To open the command palette, press ctrl+p.
Posting can be configured using a configuration file, environment variables, and/or .env
files.
Configuration values are loaded in the following order of precedence (highest to lowest):
- Configuration file
- Environment variables
.env
files
The range of available configuration will be greatly expanded in the future.
You can write configuration for Posting using YAML.
The location of the config file can be checked using the command posting locate config
.
Here's an example configuration file:
theme: galaxy
layout: horizontal
response:
prettify_json: false
heading:
visible: true
show_host: false
All configuration values can also be set as environment variables.
Simply prefix the name of the config with POSTING_
and set it as an environment variable.
For nested configuration values, use __
as the delimiter. So to set heading.visible
to false
, you can set the environment variable POSTING_HEADING__VISIBLE=false
.
For example, to set the theme to galaxy
, you can set the environment variable POSTING_THEME=galaxy
.
Posting also supports .env
(dotenv) files, which are useful if you want to swap out environment variable values depending on the environment you're working in (for example, "dev" vs "prod").
You can tell Posting to use a .env
file using the --env
option.
This option can be supplied multiple times to load multiple .env
files.
Here's an example .env
file:
POSTING_THEME="cobalt"
POSTING_LAYOUT="vertical"
POSTING_HEADING__VISIBLE="false"
Dotenv files are separate from collections, although you may wish to include them inside a collection to make it easy to version and share with others.

Posting can load custom CA bundles from a .pem
file.
The easiest way to do this is in your config.yaml
file:
ssl:
ca_bundle: 'absolute/path/to/certificate.pem'
If the required CA bundle differs per environment, you can again use the principle that all configuration can be set as environment variables which can optionally be set and loaded using --env
and .env
files:
# dev.env
POSTING_SSL__CA_BUNDLE='/path/to/certificate.pem'
Now load the dev.env
file when working in the dev
environment to ensure the dev environment CA bundle is used:
posting --env dev.env
You can specify local certificates to use as a client-side certificate:
ssl:
certificate_path: /path/to/certificate.pem
key_file: /path/to/key.key # optional
password: '***********' # optional password for key_file
Note: this feature is highly experimental.
Posting can convert OpenAPI 3.x specs into collections.
To import an OpenAPI Specification, use the posting import path/to/openapi.yaml
command.
You can optionally supply an output directory.
If no output directory is supplied, the default collection directory will be used.
Posting will attempt to build a file structure in the collection that aligns with the URL structure of the imported API.
