Python's my language of choice just in terms of language features, but Lua is significantly ahead in terms of embedding and sandboxing.

There is actually UI for inspecting storage. As long as you have no more than 20 keys stored, it shows up on the left-hand side of the page, but you have to refresh the page to get the latest. My excuse for this not being discoverable and a

* We'd be happy to be proven wrong, but we believe $4.95 converts better than $5. * We'd be happy to charge more. We have nothing to go on yet but intuition, and we think $5 is the right amount. * This is intriguing, but I think we need to

Great catch! This should properly be implemented using leases: lease.acquire('count') local count = storage.count or 0 storage.count = count + 1 lease.release('count') return {count=count} We skipped the lease just

I'm not sure what you mean. json.stringify {2,3,5} == '[2, 3, 5]', which is correct, isn't it? (Strictly, JSON has to always have a dictionary on the outside, but it's fairly standard to allow this.) We'll keep thinking about this, but I do

I'm confused about your stringify suggestion... I think the primary use of json.stringify is to send that JSON to some API or back to a browser, but nobody else would be able to make sense of the ":1". Am I misunderstanding? We don't run an

Thanks. We don't do anything special to help or hinder Lua's handling of Unicode. In general, Lua strings store bytes. This is handy when dealing with something like file uploads, but it's not always what you want for other text encodings.

Geolua looks cool. Thanks for sharing it. It sounds like we're doing some similar things. Custom allocators are definitely the way to go to limit memory usage. We also use process-level isolation to limit the amount of execution time. We're

(Sorry, can't reply to the real comment, too nested.) @aaronblohowiak, just because we reserve the right to shut something down doesn't mean that we will. We'll learn from real use what people actually do. We have our own ideas about what w

I loved AppJet, and yes, I'd call it an inspiration for what we're doing. A number of people are mentioning JavaScript. We don't have any plans yet, but we're paying attention to the feedback.

Yup, I meant "killed." (Edited, thanks.) We figure that copy/paste is a good enough way to get your scripts out, but if there's demand, it wouldn't be too hard for us to build an export. Once you create a subdomain, you own it, but you can

It's a Python app that calls into embedded Lua.

You can make HTTP requests, so you can call another script from your script, but the calls are synchronous and won't increase your timeout, so the original script will still get killed after ten seconds. No parallelism. What's the use case

New VM per script request. No, we're not using LuaJIT for now.

Our Terms ( https://www.webscript.io/terms ) do spend a little time defining "unlimited." We didn't want people to worry about it, so we went with unlimited, but as you point out "unlimited" is always a lie when finite resources are involve

Ah, good point; thank you. We'll give this some more thought.

The whole thing is a Python app, written with Flask. As you said, we do custom routing to map URLs to scripts, which we then load up in a Lua VM and execute with conventions for how we pass in the request and interpret the return value. For

Give it a try. :-) We kill runaway processes after 10 seconds.

We don't plan on supporting custom domains, because we don't think people will serve up content directly from these scripts. (We think of them more as APIs, so typically invisible to end-users.) That said, my startup's other product (www.si

by smarx 14y ago
Most of the sandboxing just comes from using embedded Lua and only whitelisting a small number of functions. We also do a little process-level isolation to prevent runaway processes.

We probably need to write a FAQ for this. Until then, the short answer is that Lua is well-designed and well-understood as an embedded language (how we use it). That means it was easy and fast for us to integrate. If we get a lot of feedbac

I'm one of Webscript's founders, and I was pleasantly surprised to see this here. We just launched this morning, and I'm happy to answer any questions.

What you're missing is that the secret isn't present. What's there is a policy, which is a way to preauthorize file uploads to S3. The policy is signed with the secret key ahead of time. It looks to me like all the fields in that form are s
