PyBreeze is a Python IDE purpose-built for automation engineers. Web, API, GUI and load testing live in one window, alongside the everyday HTTP tooling that automation work actually needs — no plugin hunting, no environment archaeology.
The main window: automation keywords highlighted in an APITestka action file, project tree on the left, run/format/debug/terminal panes below.

Three menus carry most of the IDE. Automation runs your scripts, Tools opens the utility tabs, Install fetches the modules.

Every automation run happens in its own subprocess. Output streams back into a run window while the editor stays responsive — stdout in the normal colour, stderr in red, and the process exit code at the end:
A real run: PyBreeze's own curl parser invoked through the IDE's file runner, generating a pytest test.
PyBreeze covers the full spectrum of automation testing out of the box:
| Dimension | Module | What it does |
|---|---|---|
| API | APITestka | RESTful testing with request builders, response analyzers, mock servers and assertions |
| Web | WebRunner | Browser-driven interaction and testing with driver and locator integration |
| GUI | AutoControl | Desktop automation via image recognition, coordinates, keyboard/mouse control and recording |
| Load | LoadDensity | High-concurrency performance testing for stability under pressure |
Plus:
- File Automation — file and directory operations via automation-file
- Mail Automation — report delivery via MailThunder
- Test Framework — YAML-driven execution via TestPioneer
Each module gets the same menu shape: Run (single script, batch directory, with or without an emailed report), Help (docs and GitHub open as in-IDE browser tabs), Project (scaffold a template directory), and where available a native GUI tab.
- Automation-aware syntax highlighting — the
AT_*/ GUI / Web / Load keyword sets are registered for.json, and TestPioneer's schema for.yml, on top of JEditor's language support - Code editor — built on JEditor: tabs, project tree, format checker, debugger, terminal, variable inspector and a git client pane
- Script execution — single or batch; large action files are passed by path, never through the command line, so Windows' ~32 KB argv limit is never a factor
- Report generation — HTML / JSON / XML after a run, with optional email delivery
- Integrated JupyterLab — launches as a tab, installing JupyterLab into the project venv if it is missing
- Virtual environment awareness —
venv/and.venv/are detected and used automatically
Paste a curl command from your browser's dev tools and pick a target. The parser handles method, URL, headers, bodies, basic auth, -G query parameters, -F multipart fields (uploads become files=open(...)), the --json shortcut, -d @file bodies and multi-line continuations. Repeated -H values are combined the way HTTP combines them (; for cookies, , otherwise) instead of the last one silently winning. Nothing is ever executed — it is pure parsing.
| Target: pytest | Target: APITestka JSON action |
|---|---|
![]() |
![]() |
Targets: Python requests, a ready-to-run pytest test, APITestka (Python or a [["AT_test_api_method", {...}]] action list that execute_files runs directly), and a LoadDensity Locust load test. Copy the output, open it straight into an editor tab, or save it with the right extension. One click also hands the parsed URL to the URL parser/builder or the headers to the header analyzer.
"Copy as cURL" captures one request; Save all as HAR captures the session. Open the export and every recorded call is listed with method, path, status and media type, with page furniture (CSS, images, fonts) filtered out by default.
Select what you want — or take everything listed — and generate one script using the same targets as the cURL importer. Repeated endpoints get numbered test names so no test silently replaces another; HTTP/2 pseudo-headers are dropped, and a Cookie header duplicating the recorded cookie list is removed so each value is sent once. A single selected request produces exactly what the cURL importer would. HAR is JSON, so this needs nothing beyond the standard library, and nothing is ever replayed for you.
The status code is looked up in the HTTP reference, headers are parsed, a JSON body is pretty-printed, and any JWT anywhere in the text (an Authorization: Bearer header, for instance) is decoded with its timestamp claims rendered in UTC. Each finding opens in its dedicated tool tab, pre-filled.
Reports names sent more than once, Set-Cookie entries missing Secure / HttpOnly / SameSite, wildcard CORS (and the wildcard-plus-credentials combination browsers reject outright), an HSTS max-age too short to survive a restart, CSP unsafe-inline / unsafe-eval, product banners, deprecated headers, and — for responses — the security headers that are absent. Headers carrying credentials are reported by name only; their values never enter the report.
Compare two payloads — an expected vs. actual API response, say — and get a unified diff plus a one-line added/removed summary.
Each is a tab or a dock, each has the same copy / open-in-editor / save-to-file row along the bottom.
- JWT Decoder — header and payload as pretty JSON, with
exp/iat/nbf/auth_timeas readable UTC. Inspection only: the signature is never verified and the token is never trusted. - Regex Tester —
IGNORECASE/MULTILINE/DOTALL/VERBOSE, every match with offsets, numbered groups and named groups. An invalid pattern reports a friendly error instead of crashing. - HTTP Status Reference — search the full status table (sourced from the standard library, so it stays current) by code prefix or keyword.
- JSON Format — pretty-print or minify, with a clear validation error when the input is not JSON.
- Timestamp Converter — a Unix epoch (seconds or milliseconds, auto-detected) or an ISO-8601 date-time in, every representation out in UTC. Deterministic and independent of the local time zone.
- Hash Generator — SHA-256, SHA-512, SHA-1 and MD5 at once (MD5/SHA-1 for interoperability with
usedforsecurity=False, never for security decisions). - Query ⇄ JSON —
application/x-www-form-urlencodedto pretty JSON and back; repeated keys become arrays and vice versa. - URL Parser / Builder — scheme, host, port, path, query, fragment and credentials as an editable JSON object, and back again. Brackets IPv6 literals and re-encodes query parameters for you.
A Mermaid flowchart pasted into the importer and laid out automatically.
A WYSIWYG QGraphicsScene editor: rectangle, rounded, ellipse and diamond nodes, bezier connections with edge labels, free text and images. Mermaid flowchart / graph import runs a Sugiyama-style layout (layering, crossing reduction, cross-axis alignment). Save and open as .diagram.json, export to PNG or SVG, with undo/redo, align, distribute, grid, snap and zoom. Images fetched from a URL are SSRF-validated and size-capped.
Password or private-key authentication, an interactive shell with ANSI handling and keepalive, and a lazy-loading SFTP tree with create-folder / rename / delete / upload / download. Unknown host keys are not auto-accepted: the SHA256 fingerprint is shown for confirmation on first connection (trust on first use) and persisted to ~/.pybreeze/ssh_known_hosts.
- File Tree Context Menu — right-click to create, rename, delete, copy absolute or relative paths, or reveal the item in your platform file manager. Renaming or deleting a file open in an editor tab keeps the tab in sync.
- Package Manager — install automation modules and build tools from the menu, output in the shell pane.
- Integrated Documentation — each module's docs and GitHub page open as in-IDE browser tabs.
Shown in the pre-send state. Send a selection to an LLM endpoint, then accept or reject the suggestion — the tally is kept in ~/.pybreeze/response_stats.txt. The URL is SSRF-validated, redirects are not followed, and the response body is size-capped before it reaches the panel.
Run the prthinker pipeline over the file being edited or over a Pull Request, with output streaming into a run window.
One settings form holds the inference backend (remote, local, OpenAI-compatible, Anthropic, Gemini, Cohere, Mistral, claude-cli, codex-cli), the code host (GitHub / GitLab / Gitea) and the repository. Keys and tokens are handed to the review as environment variables, never on a command line where a process list would show them — and they are masked in logs.
Create and manage the multi-step review chain: first summary → first code review → linter → code smell detector → total summary. Each step's result feeds the final summary. Files are watched, so an external edit shows up immediately.

Define reusable skill prompts (code explanation, code review), then pick one, edit it if needed, and send it to an LLM endpoint from a dedicated tab or dock. Both shown in the pre-send state — no endpoint was contacted for these screenshots.
PyBreeze inherits JEditor's plugin architecture, auto-discovered from a jeditor_plugins/ directory in the working directory. A plugin can register:
- Syntax highlighting — keyword sets and rules for any language
- UI translations — new interface languages
- Run configurations — "Run with…" for interpreted (
go run main.go) and compiled (gcc main.c -o mainthen run) languages, executed through PyBreeze'sFileRunnerProcesswith the compiled artifact cleaned up afterwards - Plugin Browser — browse and install plugins from remote repositories inside the IDE
Loaded plugins appear under their own Plugins menu with an About entry and one run action per supported suffix. See PLUGIN_GUIDE.md for the full API and worked examples (C, C++, Go, Java, Rust, and a French translation).
- English (default)
- Traditional Chinese (繁體中文)
Both dictionaries carry the same 571 keys, and a test enforces that parity so a new string can never land in one language only. Further languages can be added via translation plugins.

The editor process never runs your script. Every automation module is launched as python -m <package> in the project's interpreter with shell=False. Two daemon threads read stdout and stderr into thread-safe queues; a 100 ms QTimer drains them onto the UI thread in bounded batches. A crash, a hang or an infinite print loop in a script cannot take the IDE with it.
