A code library from the LangChain team for building AI agents that can pause, remember where they were, and pick back up later — even after a server restart — instead of losing all progress if something goes wrong mid-task.

Best alternatives to Dagic in 2026
When an AI agent needs to call five tools where three of them don't depend on each other, most agent frameworks still run them one after another, burning tokens and time re-explaining context at every step. Dagic gives agents a typed workflow language instead: the agent describes what depends on what, and independent branches run in parallel automatically. It sits deliberately between two extremes — plain sequential tool calling (safe but slow) and letting the agent write and execute arbitrary code (fast but risky) — by having a host register the available operations up front, so the agent composes them into a typed, statically-checked directed acyclic graph rather than generating free-form code. It's built on Python's asyncio (Python 3.10+ required) with a minimalist syntax focused purely on expressing data dependencies. In the project's own benchmarks against sequential LangGraph agents on math-problem tasks, it reports roughly 7x fewer tokens, 3x faster execution, and 3.6x lower cost. It's MIT-licensed, free, with 12 GitHub stars and 33 commits at time of review.
