Dagster

Asset-based orchestrator with a hosted Dagster+ control plane. Open source is free; Dagster+ starts at $10 a month plus $0.040 per credit.

Best for: Teams that think in data assets rather than tasks and want a hosted control plane with the data staying in their own cloud.

Pros

  • Asset-based model: you declare the tables you want, lineage comes free
  • Hybrid deployment keeps your code and data in your cloud; only metadata goes to Dagster+
  • Solo at $10 a month plus credits is the cheapest hosted orchestrator on the market
  • Great local development and testing story

Cons

  • Credits add up: Solo is $0.040 per credit, Starter $0.035, and serverless compute is $0.010 a minute
  • Pro and Enterprise are quote-only
  • Smaller ecosystem than Airflow
  • The Solo and Starter prices changed on 1 May 2026, so older comparisons are stale

Dagster’s founding insight is that data teams think in tables, while their orchestrators kept making them think in tasks. Declare the assets you want to exist (this table, that dashboard extract, this ML feature set) and let the orchestrator work out the runs, the lineage and the freshness checks. Once you’ve built a pipeline this way, going back to task-graph thinking feels like assembly language. That’s the pitch, and having watched it mature past 16,000 GitHub stars and steady releases (14 in the last 90 days), I mostly buy it.

Bottom line first

For a new pipeline built by a small-to-mid team, Dagster is what I’d reach for in 2026: the asset model, the local dev experience and the pricing all fit. The honest costs are a smaller ecosystem than Airflow‘s and a hosted tier where the monthly fee is the small print, not the price.

Reading the price correctly

Open source Dagster is free and self-hosted, full stop. Dagster+ is the hosted control plane, and its two entry plans changed on 1 May 2026, so distrust older comparisons. Solo is $10 a month plus $0.040 per credit; Starter is $100 a month plus $0.035 per credit. The subscription is the door charge, the credits are the meal: model your run volume before deciding Solo is a ten-dollar decision. Both carry a 30-day trial, and Pro is the quoted tier with custom structures.

The deployment choice matters more than the plan. On Serverless, your code runs on Dagster’s infrastructure and compute meters at $0.010 a minute. On Hybrid, your code and data stay in your own cloud, only metadata reaches Dagster, and there is no compute charge at all. Hybrid is cheaper, easier to get through a security review, and would be my default for anyone who already has a cloud account, which is everyone.

What the asset model buys you day to day

Lineage isn’t a diagram you maintain, it’s a byproduct of declaring dependencies. Freshness policies read naturally (“this table should update hourly”) instead of being alert rules bolted on later. Backfills and partial re-runs, the tasks that eat weekends on task-based orchestrators, become selecting stale assets and pressing go. And local development is genuinely good: run the whole graph on a laptop, test materialisations like normal Python. It’s the ergonomics gap with Airflow, more than any single feature, that converts people.

Integrations cover what a modern stack needs, dbt most natively of all: your dbt models appear as assets with everything else. The gap shows in the long tail: the twentieth vendor tool has an Airflow operator, and for Dagster you may write a little glue.

A worked month on Dagster+

Say a Starter-plan team materialises 60 assets in a nightly job, plus an hourly refresh of 8 hot tables during business hours. That’s roughly 4,600 materialisations a month, and Dagster’s pricing FAQ defines a credit as exactly that: the sum of asset materialisations and ops executed. So about $161 in credits on top of the $100 subscription, so a $260 month on Serverless before its compute minutes, or just those credits plus $100 on Hybrid with zero compute charge. Ops inside your assets count too, so graphs with many small steps meter faster than the asset count suggests; instrument one real week on the trial and multiply, rather than trusting my sketch or anyone else’s.

The pattern to notice: on Hybrid, doubling your data volume doesn’t touch the Dagster bill at all, only your own cloud’s. For lumpy workloads that predictability is the whole argument.

Signals worth weighing

Review-site coverage is thin (a 4.5 on G2 from just 2 reviews, which I’d treat as anecdote rather than evidence), so the better signals are the open ones: healthy commit flow, a release every week or so, and an unusually active Slack where the maintainers actually answer. This is a tool whose community lives in code and chat, not on review sites, which suits its audience and slightly understates its adoption.

Skip it when

Two honest cases. A working Airflow estate with no acute pain is a reason to stay put: the asset model is nicer, and nicer rarely justifies a quarter of migration on its own. And if your pipelines are wall-to-wall vendor integrations from the long tail, check the integration list first, because writing glue for six tools erodes the ergonomics win that brought you. Everyone else evaluating orchestrators fresh should have this on the shortlist, probably at the top.

Verdict

The best developer experience in orchestration, priced sanely if you read the credit line and choose Hybrid. Greenfield small team: yes without much agonising. Migrating a working Airflow estate: only if the pain is real, because rewrites are paid in quarters. Either way, run the 30-day trial against one genuine pipeline, not the tutorial, and let the asset model make its own case.

Questions people ask

What makes Dagster different from Airflow?

Dagster orchestrates around assets, the tables and files you want to exist, instead of around tasks. Lineage, freshness checks and partial re-runs come from that model rather than being bolted on.

What does Dagster+ cost?

Solo is $10 a month plus $0.040 per credit, and Starter is $100 a month plus $0.035 per credit. Pro is quoted. Serverless compute is billed at $0.010 a minute; on Hybrid, where your code runs in your own cloud, there is no compute charge. These Solo and Starter prices took effect on 1 May 2026.

What is Hybrid deployment?

Your code and data stay in your own cloud account and only metadata goes to Dagster's control plane. For a team that wants a managed scheduler without shipping data to a vendor, it is the most interesting option on the market.
