Why tf do i need to register in some cloud app just to fiddle with some http headers?
非常难用，想修改一个，单规则配置太单一，多规则顺序不能控制，无法达到预期效果
为什么现在这个插件 趋向于收费了 而且 现在登录有问题 一直选择google或者 email登录都登录不上去
ahora es paga
Was a nice tool before it became paid
Not free.
We used this to delay API responses and modify params received to see how front end would handle them - this allowed front end to re-create a range of scenarios without wasting any back enders time. Did exactly what we needed it to, would recommend
Was good until they decided to paywall a few free feature with a forced overpriced subscription, immediately uninstalled .
Works as it should, but adds its script to every page even in paused state - I don't like this and so have to manually disable it every time I finish working with it. Update: the script is called "libs/customElements.js" and, as I understand it, is part of the "Session Recording" option. It's injected into each page when requestly is enabled (paused or not, it doesn't matter), and even if it doesn't do anything, I generally don't want extensions interfering with pages when I disable them.
I was recently introduced to Requestly and used it for verifying libraries created in Adobe Launch without actually publishing them and I must say it performed perfectly. It is super user friendly and offers great ease of use.
