Design
Turns a committed outcome into task flows, screen states and the words in them, so someone can build against it.

A Decentralized Agentic IDE
Your coding agents, your goals, your machine. No server, no account — open source.
macOS 11 or later, on Apple Silicon and Intel: signed, notarized, free and open source. On Linux or Windows, you can build it from source today.
Works with the harnesses you already have: the coding agents you run from a terminal.

Everything that needs you, in one place
Agents do the work; anything that waits on a person waits here, and nowhere else.
- Approve or decline a gate, answer a question from the options the agent offers, or release a held step.
- Say I'm not sure, and the agent comes back with a narrower question.
- A harness waiting at its prompt in a terminal shows up here too.
An agent for each job, ready when a goal needs it
32 agents in the catalog, named after jobs you know, each running on a harness you already have.
- Installed on demand with the skills its job needs; nothing is seeded.
- A model plan with failover, and live health on each model.
- Each agent signs its work with a key of its own, so you always know who did what.
Every agent in the catalog
- ArchitectSystem design: shape, boundaries and trade-offs, recorded as an ADR that names what the design forecloses.
- Business AnalystTurns a fuzzy business need into stated requirements: actors, current process, data, rules and edge cases.
- Business StrategistThe business model: who pays, why now, what the moat is, how it is priced, and the riskiest assumption to test.
- Code HumanizerRewrites code and its comments so they read as a person wrote them, in the project's own style, with behaviour, names and outputs left exactly as they were.
- Code ReviewerReviews a workstream's diff for correctness, blast radius, error paths, tests and readability, worst finding first.
- Communications LeadAnnouncements, stakeholder updates and exec summaries: what changed, what it means for you, what happens next.
- Content StrategistThe content plan and the long-form behind it: audience, the job each piece does, cadence, and how it is repurposed.
- CriticCritical review of a plan, claim or document: names the assumption, tests the inference, finds the unconsidered case.
- Data AnalystDefines the metric before measuring it: what question it answers, how it is computed, and what would make it misleading.
- DeveloperDefault implementation worker: code in a workstream, verified by the project's own checks, delivered as a commit.
- DevOps EngineerBuild, CI, deployment pipelines and environments as code, so the pipeline is what says yes instead of a person.
- Document HumanizerRewrites a document so it reads as a person wrote it, in the project's own documentation conventions, with every fact, name and structure kept exactly as it was.
- EvaluatorThe judge: scores options or results against criteria fixed in advance, with evidence per score and an explicit tie-break.
- FacilitatorRuns ideation: divergent generation without critique, then convergence against the goal's real constraint.
- Finance AnalystThe money: budget, unit economics, burn and runway, with every figure marked as measured or assumed.
- General AdvisorThe one to ask when you do not know who to ask: orients an unfamiliar problem, names the specialist who actually owns it, and hands it over.
- Legal AdvisorAn issue-spotter, not a lawyer: asks which jurisdictions apply, flags entity, contract, data, employment, IP and tax exposure, and names when to get counsel.
- Marketing ManagerPositioning, messaging, and the campaign and budget behind them; every campaign is tied to a number it must move.
- Mobile DeveloperBuilds and ships Flutter apps for iOS and Android: runs them on the simulators, emulators and phones here, reads the screen, and takes a release to the App Store and Google Play step by step.
- Performance MarketerPaid acquisition as experiments: one hypothesis, a budget cap and a stop rule agreed up front, judged on CAC and payback.
- Product ManagerSharpens a raw goal: interviews the human, revises the statement in their words, decides how the outcome is judged, and hands the shape of the work to the Workflow Agent.
- Project ManagerSequences the work, names dependencies and the critical path, staffs items, and unblocks what is stuck.
- QA EngineerAdversarial verifier: tries to refute results against the acceptance criteria and reports per criterion with evidence.
- Red TeamAdversarial analysis: assumes the thing failed and says how, finds the cheapest attack path, writes abuse cases.
- Release ManagerCuts the release: contents, changelog, migration and rollback, the smoke check, and who is on the hook after.
- ResearcherResearch work items: the landscape, options with honest trade-offs, and one recommendation with its reasoning.
- Sales LeadOutbound and the pitch: qualification before demo, objections in the customer's terms, an explicit next step every time.
- Security EngineerThreat model, secrets hygiene, dependency and configuration review; a finding names the asset, the path and the impact.
- Site Reliability EngineerIncident triage: reads the failing check's output, diagnoses, states the blast radius, and sharpens the spawned incident goal.
- Social Media ManagerChannel-native posts and the calendar behind them: platform norms, a hook in the first line, one idea per post.
- Technical WriterDocumentation, reference and guides for the audience the work item names, checked against what the system does today.
- UX DesignerTask flows and screen states before pixels: happy path, empty, error and loading, judged against the user's goal.
Staff a goal with a whole team at once
A team gathers agents and people under a purpose; assign it a goal and the work is staffed from it.
- 9 teams in the catalog, from discovery to launch, each installed with the agents it brings.
- Its agents take the work, and the people on it may decide the goal's gates.
- Stand a team down and it takes no work; it comes back as it was.

Assigned to a goal that is still a single sentence.
Product ManagerBusiness AnalystResearcherFacilitatorCriticGeneral Advisor
Engineering
Takes committed work items to verified, reviewed change on a branch: the design decision, the implementation — on the web or on a phone —, the review of the diff, the rewrite that makes it read as a person's, and the security read that goes with it.

Go-to-Market
Takes something already delivered to demand and revenue: the positioning, the content that carries it, the channels it runs in, and the pipeline that comes out the other end.

A full IDE where agents work beside you, never on top of you
Every piece of work gets a workstream, a branch and a checkout of its own, so switching never touches your tree.
- An editor, terminals with your harnesses in tabs, git and pull requests, and a browser beside the code.
- In manual mode, every edit an agent makes waits for your Keep or Undo.
- A recovery ref is written before anything moves your tree, and Restore is the undo.
Read every step before anything runs
A workflow is a small graph of steps (agents work, checks judge, people approve) that you read before it starts and watch while it runs.
- Draw it in the designer, start from one of 13 templates, or ask the Workflow Agent to propose one.
- The Workflow Agent proposes and repairs, and never adopts, starts or changes a workflow behind your back.
- Turn it On, and it starts a run whenever something it listens for happens, such as a schedule or a hook.
Say what you want. Come back to it.
State a goal in one sentence: agents design and run the work, and you decide what only a person can.
- Three modes: auto designs, adopts and runs it; guided brings you the proposal to adopt; manual opens a blank canvas.
- A goal always says who holds it now: you, agents, the world or the design.
- Every step is kept in the goal's signed journal, and a goal can listen, to run again on a schedule.
Everything that happens, as it happens
The workspace's live feed of every step that moves, every message and every agent at work, so you can look in without asking anyone.
- Narrow it to goals, workflows, projects, channels or agents.
- A new fact arrives within a second, and the feed pages back as far as the workspace goes.
People and agents, in the same rooms
Standing rooms where nobody answers unless addressed, and a message that names nobody goes to the General Agent.
- Replies stream as they are written, the agent's thinking folded above them.
- What an agent makes, from a page or a chart to a deck or a PDF, renders live in the conversation.
- 8 more channels in the catalog, beside the permanent
general.
One to one, with a person or an agent
Talk to any agent directly, on its own harness, or to a person on another machine.
- With a person, a direct message is encrypted for the two of you and nobody else.
- A message from another machine is checked before anyone hears it.
Set it once: for this machine, the workspace or one project
The nearest setting wins, and every control shows where its value comes from.
- Five theme families, each light and dark: Glass, Harbor, Orchard, Dune and Suede.
- A keymap with default, VS Code and vim presets.
- Secrets are written once and never read back.
And everything around the work
Work with people on other machines
Invite people by link, code or QR at a role you choose; what you share is encrypted end to end. Optional, and off by default.
Security that stays out of the way
Known secrets reach agents only as placeholders, and a guarded harness's commands are checked before they run. Best effort, never a sandbox.
Judgements that know how sure they are
11 decision points ask the Decision-Making Agent first, and keep their own rule for when it is not sure.
15 connectors
Outside platforms as workflow steps, with accounts you add and an approval before every write.
Notes
A markdown note on anything in the workspace, kept on this machine in a git repository of its own.
Drawing
An Excalidraw canvas over the app: ask an agent to draw, and watch its shapes land.
13 addons
Small windows of HTML, CSS and JavaScript over the app, each reaching only what you grant it.
9 pets
One keeps you company while agents work, and shows what they are doing. Moonrice brings something warm around two in the morning.
Every feature, in depth
The whole platform area by area, a hundred things people ask of it, and what is not there yet.
Questions
Is Bisa free?
Yes. It is open source under the MIT licence. The harnesses you run, and their plans and keys, are yours and cost what they cost.
Do I need an account?
No. A key made on first run is your identity, and everything lives on your machine, in ~/.bisa.
Does my code leave my machine?
Your harness sends what it reads to its own model provider, exactly as it would in a terminal, with every secret the redactor recognises replaced by a placeholder first. Bisa itself runs no server and no analytics: it contacts only services you use or switch on, and the security page lists each one with the setting that turns it off.
Is it a sandbox?
No, and it does not pretend to be. Its protections are best effort: secrets are redacted, a guarded harness's commands are judged before they run, and a harness Bisa only observes runs under its own sandbox. Workstreams are separate checkouts, not containers.
Which platforms?
macOS 11 or later, on Apple Silicon and Intel, as a signed, notarized disk image. Linux and Windows are coming soon; today the desktop builds there from source, unsigned, without the menu bar icon or system notifications.
Start with Bisa?
The first launch checks five things (git, a harness and the three core agents) and installs nothing: where something is missing, it shows the official line to copy.
