genblaze is a production-grade Python monorepo SDK for orchestrating generative AI media pipelines — image, video, audio, text-to-speech, and chat — across 16+ provider integrations (OpenAI, Google Gemini/Imagen/Veo, NVIDIA NIM, GMICloud, Runway, Luma, Replicate, FAL, ElevenLabs, AssemblyAI, Hume, LMNT, Stability Audio, Decart, AtlasCloud). The public API is a chainable Pipeline/Step abstraction with batch, streaming, ingest, and agent-loop modes, plus a Click-based CLI (extract/verify/replay/index) for manifest inspection, a schema-first spec package generating TypeScript types from JSON Schemas, and ~30 runnable examples. Architecturally it is a monorepo: libs/core (genblaze-core) contains the framework (pipeline, providers, model registry, storage, media handlers, canonical hashing, signing, observability, webhooks), while each connector under libs/connectors/* is an independently versioned package registering itself via plugin entry points. Key entry points are Pipeline.run()/batch_run()/stream() for programmatic use and the genblaze command line; data flows through provider submit/poll/fetch_output lifecycles, optional caching, S3/B2 object-storage sinks with URL policies, and manifest generation that can be embedded directly into output media files. Two capabilities set this apart. First, provenance: every run produces a canonical, hash-verified Manifest (SHA-256 over deterministically serialized JSON), optionally Ed25519-signed, and byte-preservingly embedded into JPEG/PNG/WebP/MP4/audio files via XMP/atom splicing without re-encoding. Second, security and reliability engineering: SSRF protection with DNS pinning, credential redaction, ReDoS-safe pattern heuristics, ffmpeg injection escaping, configurable retry policies, model liveness probes, and discovery-aware validation (NATIVE/PARTIAL/NONE support levels) that reduces hardcoded slug rot. The project is actively maintained with unusually thorough tooling: golden hash-stability tests, a provider conformance test base class (~15 contract checks per connector), pin-parity and PyPI-metadata release gates, zizmor/dependabot CI, and live probe scripts that fail on API drift. Main risks are the inherent churn of 16+ third-party APIs (mitigated but not eliminated by mock-heavy tests) and a package/versioning layout complex enough that installs rely on documented make targets. Overall this is a strong, well-architected application SDK — suitable both for direct use and as a reference for multi-provider integration frameworks.
FeedCraft is a self-hosted feed processing service that transforms raw sources (RSS, Atom, HTML, JSON, search results, inbox pushes) into customized RSS feeds through composable processing pipelines called 'crafts'. The system is a monolith Go backend with a Vue 3 admin dashboard, exposing REST APIs for feed ingestion, transformation (AI-powered translation, summarization, full-text extraction, filtering), and aggregation into 'topic feeds'. The architecture follows a clean separation of concerns: source fetching/parsing, craft processing (atomic operations and flows), engine runtime, and administrative controllers. External dependencies include SQLite/PostgreSQL, Redis, an OpenAI-compatible LLM, a browserless service for dynamic content, and optional embedding APIs for semantic filtering. The codebase demonstrates solid engineering with interfaces for sources, parsers, crafts, and caching, though it carries some migration complexity from legacy craft models to newer ones.
