local — your data, your machine
Built for backend work
One desktop app for real integration work.
Keep the common API, protocol, mock, proxy, database and debugging workflows close together without sending project data to a cloud account.
Protocols & Streaming
gRPC, SOAP/WSDL, WebSocket, SSE and broker clients for Kafka, RabbitMQ, MQTT, Redis and NATS — first‑class.
B. ProtocolsStreaming and brokers
Infrastructure & Simulation
Mock servers, proxy/interceptor, record & replay, Docker Lab presets, and a load‑testing engine with HDR histograms.
C. InfrastructureMocks and proxy
Debugging & Analysis
Browser debug via CDP, HAR viewer, network & JSON/XML tools, dev logs, observability with trace waterfall, secret scanner.
D. DebuggingInspect and analyze
Local Data
Database Studio (SQLite, Postgres, MySQL, MongoDB, Db2), storage inspector, encrypted vault, workspaces and markdown.
E. Local DataDB and vault
Customization & Extensibility
11 themes, theme editor, Windows 95 skin, template marketplace, WASM plugin sandbox, and a full Python plugin SDK.
F. CustomizationThemes and plugins
Platform
Settings for appearance, requests, proxy, mock, vault and editor; bbolt embedded DB; portable local storage.

Local‑First by Design
No accounts. No telemetry. No hidden sync. Workspaces, logs, vaults and settings stay on your machine unless you export them.
Private by designLocal.
Core principles
Built for engineers who actually ship.
01 / Local‑first
Your data stays local.
Workspaces, settings, logs, vaults, templates and traffic captures live on your disk — not on someone else's server. Portable .adomnia files, optional Git, no lock‑in.
02 / Privacy‑first
No account, no telemetry.
There is nothing to sign up for. No usage analytics, no opt‑out dialog, no hidden cloud sync. Secrets in the encrypted vault and credentials in your workspace go exactly where you send them — nowhere else.
03 / Enterprise‑ready
SOAP, mTLS, brokers — real work.
WS‑Security, gRPC, certificate tools, SASL/SCRAM, AMQP, MQTT — the protocols mainstream HTTP clients ignore are first‑class citizens here.
