Build PlatformBUSL-1.1

Describe a piece of software and it is split into a tree of parts that can be built independently, built concurrently, each in its own workspace, then assembled bottom-up, with each part checked by an agent barred from having authored it. Self-hosted and provider-agnostic against any models including local ones: there is no SynthOrg service in the path, and what reaches a third party is whatever the provider you configured needs, or nothing at all against local models. Pre-alpha: the platform, infrastructure and agent runtime are exercised by deterministic e2e harnesses with a scripted provider, and no live run has yet produced an assembled deliverable.

~Multi-AgentDecompose, route, parallel execution and rollup run end to end, alongside assignment strategies, coordination dispatchers and conflict resolution. Exercised by a deterministic harness; a live run has not yet reached assembly
~Task DelegationDAG decomposition, assignment strategies and delegation chains run through the work pipeline end to end. Exercised by a deterministic harness; a live run has not yet reached assembly
~MemoryPluggable backends and memory types with hybrid retrieval, wired into the working loop on a durable substrate. The embedding model is the operator's explicit choice and memory stays off until it resolves
~Tool UseMCP protocol, per-category sandbox isolation (subprocess by default, Docker where an operator selects it) and invocation tracking run inside the agent runtime. Exercised by a deterministic harness; a live run has not yet reached assembly
✔Human-in-the-LoopApproval gates, review workflows, and four operator-set oversight modes run today: a sensitive action parks with no side effect and resumes on a human decision
✔Budget / CostPer-token and per-agent budgets, hierarchical cascades, a pre-flight forecast gate, and a hard run ceiling that parks execution. An agent is a fixed (role, model) pair that nothing re-points, so budget pressure refuses rather than silently substituting a cheaper model
✔SecurityRule engine plus LLM evaluator, classified action types, audit trail, and output scanning gate every action and fail closed. The adversarial red-team gate is staffed from the roster and applies from high stakes upward
✔ObservabilityStructured logging, correlation tracking, log shipping, redaction, Prometheus metrics, and OTLP ship and run today
✔DashboardReact 19 dashboard (org chart, tasks, budgets, approvals, workflow editor, setup wizard, WebSocket + SSE) ships and runs; polish against real workloads continues
✔CLIGo binary for container orchestration and supply-chain verification; deliberately not used for agent orchestration
~Production ReadyInfrastructure ships (Docker + CI/CD + cosign + SLSA L3, SQLite + PostgreSQL backends, backup/restore); the product is pre-alpha. The loop has been driven live against a real deployment and has never reached the assembly stage, so no assembled deliverable and no recorded completion exists
~WorkflowsSequential, parallel, Kanban, Agile sprints and velocity execute through the agent runtime. Exercised by a deterministic harness; a live run has not yet reached assembly
✔TemplatesCompany templates and locale-aware name generation ship and are usable today without the runtime

Rows are compiled from each project's own documentation and repository, and may have drifted since. The table includes SynthOrg's own row, so it shows one more entry than the 44 it is compared against.

Where SynthOrg is uniquely different

Split into a tree, not held in one loop

A single agent holds one thing at a time, so that shape degrades as an application grows. Here a build is split into a tree of independently buildable units, the leaves built concurrently, each in its own workspace, and assembled bottom-up. Making the parts genuinely independent is the hard problem, and the one the system is built around.

The reviewer did not write the work

A finished unit is judged by a different agent, chosen per review with the author excluded from the pool. The exclusion is structural, not a convention: the service layer removes the author, and a database constraint refuses any verdict whose executor and reviewer match. An independent judge is a triage filter, not a correctness guarantee.

It runs on your hardware

Containers you start, a database you hold, credentials you register. No SynthOrg service sits in the path and no provider is privileged: every dispatch names a provider and model you chose, including models you run yourself. Spend lands on your own accounts rather than a metered platform bill.

Supervision is a property, not a stage

Actions route through an approval gate under an oversight mode you set (full, semi, supervised, locked), with an audit trail behind it and a sandbox around tool execution. Autonomy is never granted by an agent to itself: widening it is a human act, and a failed check keeps the action gated.

Frequently Asked Questions

Why not just use CrewAI or AutoGen?
CrewAI and AutoGen are excellent frameworks with strong communities and proven track records. CrewAI excels at role-based agent crews with a clean developer experience. AutoGen is powerful for conversation-driven agent systems (now in maintenance mode, with Microsoft pointing new projects at the Agent Framework instead). SynthOrg targets a different problem: splitting a software build into a tree of independently buildable parts, building the leaves in parallel, each in its own workspace, and checking each with a reviewer barred from having written it. If your use case is a multi-agent pipeline or crew, CrewAI or AutoGen may be simpler and more mature. If you need that decomposition-and-check machinery, SynthOrg is built for it, though the loop has not yet completed a build end to end.
How is SynthOrg different from ChatDev or MetaGPT?
ChatDev and MetaGPT simulate a fixed cast of company roles working through a scripted code-generation process. SynthOrg's approach is structural rather than role-based: a build decomposes recursively into a tree of independently buildable parts, the leaves build concurrently, each in its own workspace, and each is checked by a reviewer barred from having written it. It also ships the production infrastructure (Docker, dual-backend persistence, backup/restore, observability) that research projects typically lack. The loop is pre-alpha and has not yet reached an assembled result.
Is SynthOrg production-ready?
Not yet, and we are specific about why. The platform and infrastructure are built and tested (Docker images with Wolfi apko-composed distroless base, cosign verification, SLSA provenance, backup/restore, structured logging with redaction, dual-backend persistence, API, dashboard, CLI). The loop has been driven live against a real deployment with real models twelve times, and has never once reached the assembly stage: no run has produced a completed, checked build. We rate ourselves 'partial' on the capabilities that depend on that outcome and 'full' only on what verifiably ships. Recommended for evaluation and following along, not production workloads.
What about LangGraph for complex workflows?
LangGraph excels at graph-based agent workflows with checkpointing, and leaves decomposition, review, and infrastructure to the application built on top. SynthOrg decomposes a build recursively into a tree, runs it through sequential, parallel, Kanban, or Agile-sprint workflows, and checks each leaf with a reviewer barred from having written it, alongside budget tracking and security policy enforcement. That loop has not yet completed a run against real models end to end.
Does SynthOrg support my LLM provider?
SynthOrg uses LiteLLM under the hood, supporting 95+ LLM providers out of the box. It adds multi-provider routing, budget-aware model selection, and per-agent cost tracking on top.
What about commercial platforms like Bedrock, Vertex, or Agentforce?
Cloud platforms like Amazon Bedrock Agents, Google Vertex AI Agent Builder, and Salesforce Agentforce offer managed infrastructure, enterprise compliance, and deep ecosystem integration. The trade-off is vendor lock-in and less control. SynthOrg is self-hosted and source-available (BUSL-1.1), giving you full control over your infrastructure, data, and agent behaviour, but you manage the ops yourself. If your organisation already lives in AWS, GCP, or Salesforce, their native agent platform may be the pragmatic choice.
What license is SynthOrg under and what does it mean?
SynthOrg uses the Business Source License 1.1 (BUSL-1.1), a source-available license. You can freely use it in production for any purpose that does not compete with SynthOrg as a product. Small organisations building internal tools, automations, or custom agents are free to use it without restriction. Each released version automatically converts to Apache 2.0 three years after its release date (the current version's Change Date is April 2, 2029). Once converted, the code is fully permissive with no additional conditions.
Is this comparison data accurate?
We research each competitor by reviewing their official documentation, GitHub repository, and recent release notes. Evaluations follow a consistent rubric (full, partial, planned, none) applied equally to SynthOrg and every competitor. That said, frameworks evolve quickly and we may occasionally lag behind. If you spot an inaccuracy, please open a GitHub issue; we will correct it promptly.
