PyPepper
Composable building blocks for Python microservices.
Build faster. Live more.
In memory of my father, who passed away in 2023 from COVID-19.
PyPepper is a small toolkit—not a full framework—for wiring services: HTTP / SSE, FSM, a workflow scheduler, signed events, thin DB helpers, and optional OpenTelemetry tracing. Supports Python 3.10–3.14.

Highlights
| Network | FastAPI HTTP + SSE; header API-key auth and rate limits (auth-off needs PYPEPPER_SSE_ALLOW_AUTH_OFF) → guide |
| FSM & events | Rollback on handler failure; signed JSON payloads → guide |
| Scheduler | Rounds, soft timeouts, and retries; durable job-store fail-fast → guide |
| Tracing | Opt-in OpenTelemetry (console / local Jaeger) → guide |
| Quality | PEP 561 py.typed · ruff + mypy CI · line + branch coverage ≥ 90% |
| Data | Thin DB helpers → guide |
Quick start
Requires Python 3.10–3.14. uv ≥ 0.10.7 is recommended for local installs.
make build-prepare
SSE example (set a key; default config enables authentication):
export PYPEPPER_SSE_API_KEY=your-local-key
python example/sse/app.py
HTTP example:
python example/server/app.py --config ./conf/app.config.yaml
Scheduler end-to-end example: python example/scheduler/app.py.

Developer commands
make lint # ruff + mypy
make check # lint + mutable class-attr guard
make test # check + pytest (coverage ≥ 90%, branch on)
make docs # mkdocs build --strict
make audit # pip-audit on production requirements
make docker # local image
make clean

Release tags: docs/guides/release.md.
Security
See SECURITY.md for supported versions and private reporting.
Leaving SSE authentication off without PYPEPPER_SSE_ALLOW_AUTH_OFF is rejected by the library (HTTP 503).
