Framework you assemble vs runtime you run
LangChain is a developer framework — a box of parts for building agent systems in code. AGNT is a running product: visual workflows, a marketplace, receipts and a local runtime, usable the hour you install it.
Where they differ
Code-first vs product-first
LangChain assumes engineers assembling components; AGNT ships working surfaces non-engineers operate.
You host vs it runs local
LangChain apps need your own infra and glue; AGNT Community Core runs on your machine, free.
Observability
LangSmith is an add-on service; AGNT receipts are built into every run by default.
Time to first result
A LangChain agent is a coding project; an AGNT agent is a download and a prompt.
Which should you pick?
Choose LangChain if
You are an engineering team building a bespoke agent product and want maximum programmatic control.
Choose AGNT if
You want agents working on real business tasks today, with verification, without building a platform first.

How they compare, property by property
| Property | AGNT | LangChain |
|---|---|---|
| What it is | A runtime you install and run | A library you build with |
| Time to a working agent | Minutes | Days, plus the code you maintain |
| You maintain the plumbing | No | Yes — all of it |
| Ceiling on customisation | High — custom nodes and code steps | Unlimited |
| Ecosystem size | Younger, growing | The largest in the category |
| Visual canvas | Yes | No — it is code |
| Runs without writing code | Yes | No |
| Version control on the logic | JSON workflows in git | Real source, real git |
| Testing story | Run it and read the receipt | Whatever you write |
| Choose the model per step | Yes, in the UI | Yes, in code |
| Local model support | First-class | Supported |
| Scheduling and triggers included | Yes — built in | No — you supply the runner |
| Credential management included | Yes — a local vault | No — you supply it |
| Approval gates included | Yes | No — you build them |
| Audit trail included | Yes — a receipt per run | LangSmith, separately priced |
| Deploys as a product feature | Not the design target | Yes — that is the point |
| Team needs an engineer | No | Yes |
| Vendor lock-in | None. Workflows are JSON | None. It is your code |
| Best fit | Automating work you do today | Shipping agent features in your own product |
| Can they be used together | Yes — call a LangChain service from a node | Yes |
Across 20 properties: AGNT leads on 9, LangChain leads on 5, and 6 are a genuine draw. Total control, an enormous ecosystem, and the right answer when you are building a product rather than automating your own work.
What it costs at three real usage levels
| Monthly volume | AGNT | LangChain |
|---|---|---|
| A few hundred runs a month | $0 — Community Core | Usually inside a free or starter tier |
| Around 10,000 runs a month | $0 — Community Core | Typically $50–$300/mo depending on step count |
| 100,000+ runs a month | $0 — Community Core, plus your own model costs | Typically $500–$1,600/mo, plus AI usage |
AGNT runs on hardware you already own, so the marginal cost of a run is electricity plus whatever the model call costs you directly. Hosted tools meter the run itself.
