What it is

Kortix (formerly Suna) keeps agents, shared skills, company memory and connectors in a git repo you own, defined by a kortix.yaml scaffolded from its CLI. Each session runs on an isolated cloud computer on its own branch, and the work an agent produces lands through a change request a human approves. It runs on any provider with your own API keys, self-hosted or on Kortix's managed cloud.

Los Agentes on Kortix

Who are they?
The ruling
El JuezThe judge

El Hacker and La Jefa split over the same deployment: his self-hosted Apache-2.0 build and her $2,400 a month on somebody else's machines.

Adopt with conditions
Reasoning and trade-offs · AI analysis

El Hacker scores it highest for Apache-2.0, an MCP client and a documented self-hosting path. La Jefa scores it lowest: "$2,400 for sixty engineers before a single unit of consumption", with source code executing on vendor infrastructure by default. El Crítico calls the same arrangement two meters where "nothing rewards finishing quickly".

El Hacker's reading wins only where he actually runs it himself, and at the default settings he is overruled, because the vendor's machines and the vendor's meter both apply. La Jefa's pilot shape is the correct one. Adopt with conditions, the conditions being a self-hosted pilot of under ten seats and a spend alarm set in week one.

El AmigoThe friend

Pick Kortix if you want every agent session on its own branch in an isolated cloud machine; pick OpenHands if you would rather not think in credits at all.

6.3
Reasoning and trade-offs · AI analysis

The trait that decides it is isolation per session. Each run gets its own cloud computer and its own branch, so two agents working at once never trip over each other and a bad run is thrown away rather than untangled. If you have ever watched two agents fight over the same working tree, you already know why that matters more than any feature list.

What you pay for it is a bill shaped like credits and a dependency on somebody else's machines unless you self-host. Pick it for parallel ticket work with review. Pick OpenHands if credits annoy you.

El CríticoThe critic

The paid tier charges a seat and then charges usage on top, so an agent that browses and retries has two meters running and no reason to stop early.

5.5
Reasoning and trade-offs · AI analysis

The risk is the metering shape. The published plan structure puts consumption on top of a per-seat charge, and the unit of consumption is sandbox time for an agent that can browse, run commands and retry. Nothing in that arrangement rewards finishing quickly, and the cost of a task that loops is borne by the buyer rather than the vendor.

Set an alarm before the first week, not after the first invoice. What it does right: the output arrives as a change request a human approves, so an expensive run still cannot merge itself into your main branch.

El ProfesorThe professor

Configuration is a kortix.yaml scaffolded into a repository you own, with agents, shared skills, company memory and connectors stored as versioned files rather than platform state.

6.5
Reasoning and trade-offs · AI analysis

The design decision worth noting is where state lives. Agents, shared skills, accumulated memory and connectors are files inside a repository the customer owns, declared through a kortix.yaml the command line scaffolds. Context for a run is therefore reconstructible from version control rather than read out of a vendor database, which makes a past run auditable in principle.

No benchmark is published and the row carries no methodology to examine, so effectiveness is claimed rather than demonstrated. The file-as-configuration choice is principled and should survive model changes; the absence of measurement is the gap.

La InversoraThe investor

Twenty thousand stars and a free tier metered at 200 sandbox credits, with enterprise terms behind a conversation, is open-source distribution converted into a compute margin.

7.0
Reasoning and trade-offs · AI analysis

The shape of this business is legible. Twenty thousand stars supply the funnel, a free allocation of 200 sandbox credits supplies the trial, and enterprise terms sit behind a conversation where the margin actually gets negotiated. The company is reselling compute wrapped in a workflow, which is a real revenue line and also a thin one when clouds compete on the same input.

Moat: the repository-native configuration creates switching cost once a team's skills and memory live there. Likely acquirer: a developer cloud that wants an agent front end for its sandboxes. Position: long the category, watch the gross margin.

La JefaThe CTO

Team seats run $40 each, so sixty is $2,400 a month before consumption, and the code sits on vendor machines unless we take on running it ourselves.

5.5
Reasoning and trade-offs · AI analysis

The arithmetic first. Team seats are $40 a month, which is $2,400 for sixty engineers before a single unit of consumption, and consumption is the line I cannot forecast in a budget cycle. The alternative is standing it up ourselves, which converts a subscription into a platform team's quarter.

Source code executes on vendor infrastructure by default, so this needs a data processing agreement before anyone signs in, and no single sign-on or audit trail is documented outside custom enterprise terms. It has no unattended pipeline mode either. Approved with conditions: eight seats, self-hosted pilot, security review first.

El HackerThe tinkerer

Apache-2.0, an MCP client, and a curl install for a thing I can also self-host, which is most of what I ask, minus any local model path.

7.8
Reasoning and trade-offs · AI analysis

Apache-2.0 on a twenty-thousand-star codebase means the fork question is already answered: enough people care that a hostile licence change would produce a community build within days. It speaks MCP as a client, so my own servers become tools without me writing adapters, and self-hosting is a documented path rather than an enterprise favour.

The miss is local inference, which is not supported, so the model call always leaves my network even when the sandbox does not. I will take the deal, because everything else here is mine to change, but I notice the hole.
