Question 1

What is SoliTrace?

Accepted Answer

SoliTrace is a developer tool that live-captures HTTP, gRPC, gRPC-Web, WebSocket, WebRTC and MQTT-over-WebSocket requests on a single endpoint, answers them automatically with a rule engine (including SSE streaming), and can call out via cron or manually. It is a multi-protocol alternative for webhook.site-style request-bin/inspector needs.

Question 2

Which protocols does it support?

Accepted Answer

HTTP, gRPC, gRPC-Web, WebSocket, WebRTC data channel and MQTT-over-WebSocket are captured. Rule-based responses cover HTTP status/header/body templates and delay, gRPC status/message, all WebSocket frame types, SSE streaming and MQTT PUBLISH responses. Outbound calls support HTTP, gRPC, gRPC-Web and WebSocket.

Question 3

Is there a free plan?

Accepted Answer

Yes. The free plan requires no credit card; it includes a monthly request quota, a short retention period and HTTP capture with a single project. You can upgrade to paid plans from the billing section in the dashboard for all protocols, a higher quota, longer retention and team features.

Question 4

How does request capture and rule-based response work?

Accepted Answer

You create an endpoint and point your clients at that address. Every incoming request appears in a live stream with its headers/body/query, gRPC and WebSocket frames, WebRTC messages and MQTT packets. Rules you define based on conditions (protocol, path, method, header, query, body, JSONPath, frame type) generate automatic responses to the request.

Question 5

How long is captured data retained?

Accepted Answer

Retention depends on your plan: on the free plan captured data is deleted automatically after a short period, while paid plans have longer retention. Details are explained on the Privacy Policy page.

Question 6

Is there team and role-based access?

Accepted Answer

Yes. Within an organization there are owner, admin and member roles; each project and endpoint is tracked in the organization context and who can do what is limited by role.
