The latest CI/GitHub Actions builds have a fix for this implemented already! I'll be publishing another beta once I have enough time to QA all the latest changes on the Fritter and Twitter side.
I use Fritter and love it, thank you for your efforts! It's a great way to open Twitter links when necessary, since I've deleted the official app from my phone and I'm trying not to log in to my account for now.
Could you say a little about how Fritter works without an API key? Is it just because it isn't designed for posting or interacting with Twitter, just reading/viewing it? Why/how does Fritter still work when Twitterrific etc. are dead? Are you just, like, scraping the website? Isn't Twitter making it harder to read tweets from the open web when you're not logged in?
I work at Boomi, on their Flow product (similar to this project), and we open source everything in our product, except for our core workflow engine - https://github.com/manywho (our pre-acquisition name if you're wondering).
The community part is hard to generate though... there's a lot of enterprise in the workflow space.
StandardLib also has a community, though not sure how big it may be.
Pricing is a key differentiator. My market research included a pricing analysis and Boomi was priced well above Zapier and other similar solutions.
I think there is a LOT of money ceded to less expensive offerings by 10 or 15 providers (including Boomi) all chasing the same enterprise market. I would've expected tiered pricing to emerge to a greater extent, but haven't seen it.
