OpenBidKit_Yibiao
OpenBidKit_Yibiao is an open-source, free desktop application for AI-assisted proposal and bidding document generation, targeting Chinese procurement contexts. It integrates with multiple LLM providers (OpenAI, DeepSeek, local models via Ollama) and provides knowledge base management, document deduplication checking, and risk assessment features.

What OpenBidKit_Yibiao is
Built as an Electron desktop app (Windows/macOS) using React 19, TypeScript, and Vite on the frontend, with Node.js backend services for document parsing, LLM orchestration, and local file/cache management. Supports multi-model inference and includes OpenCode binary integration for code generation tasks.

Best use cases
Implementation considerations
- Desktop deployment: Users must install Electron app on Windows or macOS; no web-only or Linux version mentioned. IT provisioning and update management differ from cloud SaaS.
- LLM API credentials and costs: Each team member configures their own API keys (OpenAI, DeepSeek, etc.); no centralized billing or token pooling visible. Cost control and security of API credentials require policy.
- Local file and cache management: Generated documents, configs, and cache live in Electron userData directory; backup and disaster recovery planning is the team's responsibility.
- Knowledge base curation: RAG quality depends on training data quality and relevance; teams must invest in populating and maintaining internal knowledge bases for best results.
- Document parsing: Supports local parsing and MinerU integration; complex or non-standard document formats may require validation and custom parsing logic.
When to avoid it — and what to weigh
- Require real-time cloud collaboration or version control — This is a desktop-first tool with local storage. Teams needing simultaneous multi-user editing, cloud sync, or Git-style proposal versioning will find the architecture limiting without substantial customization.
- Need SaaS with enterprise SLAs and compliance certifications — Self-hosted open-source software does not inherently provide SOC 2, HIPAA, ISO certifications, or uptime guarantees. Organizations with strict regulatory or procurement requirements should evaluate commercial alternatives.
- Non-Chinese language or non-procurement workflows — The project is Chinese-first and optimized for tender/bidding language and structures. Adaptation to other languages, document types, or industries is possible but requires development effort.
- Expect production-grade support or SLA guarantees — Community-driven open-source project; response times for bug fixes or feature requests are unpredictable. No commercial support tier is evident in the materials provided.
License & commercial use
Licensed under AGPL-3.0 (GNU Affero General Public License v3.0). This is a copyleft license requiring that any modifications or network-distributed versions of the software must make source code available to users under the same license. Modification for internal use is permitted; redistribution or SaaS deployment triggers source code disclosure obligations.
Internal/private business use for proposal generation is permitted under AGPL-3.0. However, if your organization modifies the code or deploys it as a service to external users or clients, you must make all modifications available under AGPL-3.0. Any commercial offering (e.g., hosted platform, white-label SaaS) likely triggers disclosure requirements. Consult legal counsel if commercialization is planned; the license does not grant a commercial license, only use rights subject to copyleft obligations.

Local storage of API credentials in Electron userData directory requires secure OS-level file permissions; no mention of encryption at rest. Data in transit to LLM APIs depends on HTTPS and API provider security. No security audit, vulnerability disclosure policy, or threat model provided. Users are responsible for managing API key rotation, access control, and compliance with data residency laws if sensitive proposal content is processed.
Alternatives to consider
ChatGPT / Claude (direct or via API)
General-purpose LLMs with no proposal-specific tools; requires manual prompt engineering and document handling. Cloud-based, no local control. No knowledge base or risk-checking features. Higher per-use cost without volume discounts.
Commercial proposal software (e.g., PandaDoc, Proposify, Qwilr)
Proprietary SaaS with built-in templates, collaboration, e-signature, and analytics. Higher cost (often $50–500+/month), but no self-hosting burden, vendor support, and compliance certifications. Vendor lock-in and data residency constraints.
Microsoft Copilot for Microsoft 365 + custom document templates
Integrated into Office ecosystem; leverages existing M365 licenses. No specialized procurement/bidding features; requires extensive custom template development. Cloud-based; less transparency into model behavior and data handling.
