Team@Once is an open-source AI-driven development outsourcing marketplace that eliminates traditional risks through intelligent automation, AI-powered assessments, escrow payments, and real-time project management. Built for businesses looking to outsource development and dev teams looking for clients, Team@Once replaces fragmented toolchains with a single integrated platform.

Unlike Upwork that charges 10-20% fees with limited project tools, or Toptal that gates access behind expensive vetting, Team@Once gives you a self-hosted, low-fee platform with built-in collaboration, AI matching, and full control over your data.

Team@Once — Open-source AI-driven development outsourcing platform

1. Post or Discover -- Clients post projects with requirements; the AI engine matches them with the best-fit development companies based on skills, track record, and availability.
2. Assess & Contract -- Developers showcase verified skills through AI-generated assessments and certificates. Smart contracts are auto-generated with milestones and e-signatures.
3. Build & Collaborate -- Teams work together with built-in project management, real-time chat, video calls, shared whiteboards, and milestone tracking.
4. Pay & Review -- Milestone-based escrow payments release funds only when deliverables are approved. Both sides leave verified reviews.

• 🤖 AI-Powered Matching -- NLP-based engine matches projects to the best-fit development teams using skill vectors and track records
• 💰 Escrow Payments -- Milestone-based Stripe escrow ensures developers get paid and clients get quality work
• 📹 Built-in Video Calls -- LiveKit-powered video conferencing with screen sharing, no third-party tools needed
• 📊 Project Management -- Kanban boards, milestones, deliverables, and time tracking in one place
• 🎓 Learning & Certification -- AI-generated assessments, courses, learning paths, and verifiable certificates
• 🔍 Smart Discovery -- Qdrant vector search + web crawling data engine for finding and enriching company profiles
• 📝 Smart Contracts -- Auto-generated contracts with e-signature and milestone-linked payment terms

Outsourcing software development is broken. Businesses waste weeks vetting agencies, overpay platform middlemen, juggle disconnected tools for chat, project management, and payments, and still end up with misaligned expectations and failed deliveries.

Common pain points we address:

• ❌ High platform fees -- Existing marketplaces charge 10-20% or apply hidden markups
• ❌ No transparency -- Clients can't verify developer skills beyond self-reported profiles
• ❌ Tool fragmentation -- Teams use Slack + Jira + Zoom + Wise + DocuSign separately
• ❌ Payment disputes -- No built-in escrow or milestone-gated payment protection
• ❌ Vendor lock-in -- Your data, conversations, and project history trapped in proprietary platforms

✅ 3-5% platform fee -- Open-source and self-hostable, dramatically lower costs

✅ AI-verified skills -- Automated assessments, certificates, and portfolio verification

✅ All-in-one workspace -- Chat, video, project management, contracts, and payments unified

✅ Escrow protection -- Milestone-based payments via Stripe protect both parties

✅ Full data ownership -- Self-host with Docker Compose; your data never leaves your infrastructure

1. Fully open-source and self-hostable -- No vendor lock-in, no data leaving your infrastructure, AGPL 3.0 licensed
2. AI-native from day one -- Matching, assessments, contract generation, and content analysis all powered by AI
3. All-in-one platform -- Replaces 5+ separate tools (marketplace + PM + chat + video + payments + contracts)
4. Developer-first learning -- Built-in courses, certifications, and learning paths make it a growth platform, not just a gig board
5. Pluggable architecture -- Swap search providers (Qdrant/Meilisearch/Typesense), storage (S3/MinIO), AI (OpenAI/Ollama), and email with config changes

Total Contributors		Growing community of developers worldwide
Total Commits		Active development across all modules
Monthly Commits		Consistent monthly development cadence

Documentation		API docs, module READMEs, Swagger/OpenAPI

• ✅ Invoicing system -- Full invoice generation and tracking
• ✅ Portfolio module -- Company and developer portfolio showcase
• ✅ Install wizard -- Interactive setup wizard for new deployments
• ✅ Multi-provider video -- Pluggable video conferencing providers
• ✅ 11-language i18n -- Full internationalization coverage
• ✅ Docker one-command setup -- Single docker compose up starts everything

Run the entire platform with a single command -- no Node.js, no database setup:

git clone https://github.com/teamatonce/teamatonce.git
cd teamatonce
docker compose up --build

The first build takes a few minutes (downloading images + installing dependencies). Subsequent starts are much faster thanks to Docker layer caching.

Database migrations run automatically on startup. Once you see Team@Once Backend is running on: http://localhost:3001, open:

To stop everything:

docker compose down

To stop and remove all data (clean start):

docker compose down -v

Optional services can be enabled with profiles:

# Enable Meilisearch and local email capture
docker compose --profile meilisearch --profile maildev up --build

Available profiles: meilisearch, typesense, minio, maildev, ollama

# Start PostgreSQL, Redis, and Qdrant
docker compose up -d postgres redis qdrant

# PostgreSQL -- create the dev database
createdb -U postgres teamatonce_dev

# Update DATABASE_PASSWORD in backend/.env to match your PostgreSQL password

cd backend
cp .env.example .env    # credentials already match docker-compose.yml
npm install
npm run migrate
npm run start:dev

cd frontend
cp .env.example .env
npm install
npm run dev
