## Health v2 (maintenance only)
Score: 86/100 (v2, computed 2026-09-03T02:39:23.370411+00:00)
- activity 99, release rhythm 87, longevity 55
- inputs: {"age_days": 775, "days_push": 7, "days_rel": 8, "gap_med": 7.0, "n_releases_24m": 77}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
DBOS Transact is an open-source library (Python and TypeScript SDKs) that adds lightweight durable workflows to applications by checkpointing workflow state in Postgres or SQLite. It provides durable queues, scheduling, notifications, and automatic recovery from failures without external orchestration infrastructure.

## Use cases
- build fault-tolerant payment processing that survives server crashes
- run long-running data pipelines that resume from checkpoints after interruption
- orchestrate microservice workflows without a separate orchestrator like Temporal
- make AI agents resilient to failures and support human-in-the-loop workflows
- schedule cron jobs and background task queues backed by Postgres
- add durable execution to an existing Python or TypeScript app with a few annotations

## When to choose
- your app must reliably recover from crashes, restarts, or network failures
- you want durable workflows and queues with no extra infrastructure beyond Postgres
- you need long-running or agentic workflows with checkpointing and observability
- you prefer a lightweight library over heavyweight external orchestrators

## When to avoid
- your workflows are short-lived and failure recovery is trivial
- you cannot use Postgres (or SQLite) as a system database
- you need a language other than Python, TypeScript, Go, or Java
- you want a fully managed orchestration service with its own control plane
