Questions about alternatives to Voiceflow
What is the best open source alternative to Voiceflow?
By GitHub stars it is Langflow, with 156,612 stars and a commit on 13 Nov. Choose Langflow when you want to build and host agents yourself at no cost, since Voiceflow shows its prices only after you sign up. Next come Tiledesk (329 stars).
Is there a free alternative to Voiceflow?
Yes. The code of all 2 is public under MIT, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.
How do I choose between them?
Start from the job you use Voiceflow for. Choose Tiledesk when you want to host it yourself and keep your data on your own server.
Which Voiceflow alternatives can I host on my own server?
All 2: Langflow and Tiledesk. Each tool's page says what it needs to run.
Which ones are still being worked on?
All 2 we track had a commit in the last 30 days, among them Langflow and Tiledesk. A recent commit shows the project is kept up, not that it will stay that way.
What licences do they use?
MIT (2). MIT, BSD and Apache let you change and reuse the code freely.
What do I lose by leaving Voiceflow?
The hosting. Voiceflow's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
