Multi Protocol Platform

REST first. Everything else, consistently.

REST

HTTP/HTTPS, métodos, headers e body com UX focada em velocidade.

Available

SOAP

XML, envelopes SOAP, headers e resposta com indentação no workspace.

Available

GraphQL

Queries, mutations e schema introspection.

Available

Kafka

Streaming e tópicos; veja a página /app/kafka para o plano.

Planned

WebSocket

Conexões persistentes e mensagens em tempo real.

Available

gRPC

Protobuf, explorer e unary; veja a página /app/grpc. Contratos e microserviços.

Coming soon

GraphQL studio

Query, variables and response — with schema explorer roadmap. 

query Users($limit: Int!) {
  users(limit: $limit) {

Realtime Observability

Dashboards, streams, monitoring, profiler and traffic inspection — designed to debug production-like behavior.

Dashboards

Realtime views and streams (roadmap).

Monitoring

Uptime, health and alerts (roadmap).

Profiler

Waterfall & latency analysis (roadmap).

Traffic

Inspect HTTP traffic and debug quickly.

AI Powered (Optional)

AI when you want it. Full control when you don't.

AI requests

Generate requests from prompts (roadmap).

AI debugging

Analyze responses and fix issues (roadmap).

AI docs

Generate documentation and guides (roadmap).

AI OpenAPI

Infer specs and schemas from traffic (roadmap).

AI is optional: never send secrets/tokens/passwords automatically. Providers and payload sharing are explicit opt-ins.

AI assistant panel

Clean, optional and action-oriented — not a generic chatbot.

Prompt

Generate a request for “List users” with auth.

Suggestion

GET /v1/users (Bearer token)

Safety

Never send secrets automatically. Opt-in required.

Built for Developers

CLI, SDK, plugins, git-native collections, workflows and AI tooling — designed for real automation.

Public SDK

Local-first developer APIs for automation and external tooling (roadmap).

Git native collections

Version your collections like code: diff, history, branches (roadmap).

Workflows

Chain requests, build automation, and run repeatable flows.
