Knockout API vs MockAPI

Knockout API provides image and video processing through a browser app and API. Its image tools cover background removal and replacement, batch processing, masking, smart crop, stickers, outlines, shadows, and inpainting; the API also handles upscaling, portrait restoration, colorization, and object removal. Video background removal runs asynchronously, with job polling for progress. The browser Canvas supports layered designs with text and effects, and users can save canvases and cutouts to a free account. Developers can connect through REST, any HTTP client, or official Node, React, Python, and CLI options. The service says it manages GPU processing, endpoint updates, usage records, credentials, teams, and billing. Its privacy policy says uploaded images are processed in GPU worker memory, not retained after the response, and not used to train models. The Free plan is free, with 30 images per month and 60 requests per minute. Pay-as-you-go is $0.02 a month, with metered usage billed monthly; Plus is $10 a month. Paid tiers have no monthly cap and a 600-request-per-minute limit.

MockAPI lets users create REST API endpoints, generate custom data, and operate on it through a RESTful interface. Each project receives a unique base URL shared by its endpoints. Users define resource schemas and field-level generators, including Faker.js functions such as lorem.sentences and datatype.boolean. Relations between resources can be configured, with endpoints generated automatically. Generated resources support GET, POST, PUT, PATCH, and DELETE operations. Listed query capabilities include pagination, sorting, filtering, data generation, and customizable responses, and OpenAPI import is supported. The service is described for prototyping, testing, and learning. Documentation covers projects, resources, data generation, code examples, filtering, pagination, and relations. The Free plan costs nothing for 1 project and 2 resources. Paid monthly access costs $5 a month, and paid annual access costs $35 a year; each paid plan allows 20 projects and 50 resources. Custom endpoints and webhooks are marked coming soon.
