Corrade is a multi-purpose scripted agent (bot) that runs under Windows as a service without any graphical interface and stays connected to a Linden-based grid (either Second Life or OpenSim) while being controlled entirely from in-world LSL scripts or external scripts that can perform HTTP requests (such as PHP, Perl, Node.JS etc...). We like to think of Corrade as a bridge, that gives access to viewer-commands to LSL scripts that would not normally be able to perform advanced actions. Corrade does not stop at providing viewer-commands to LSL scripts but bundles a whole load of tools that can be used to enhance the Second Life experience:
Whilst LSL scripts offer a more convenient language to deal with in-world assets Corrade bundles functionality that is not available to LSL. Corrade could be compared to LSL's RLV extension, where Corrade provides additional viewer-side, or out-of-world features (artificial intelligence) to LSL scripts that are inaccessible or difficult to implement in pure LSL.
Corrade assumes an LSL part and a C# client which makes the bot flexible and easily configured for multiple users and groups. Each group configured in Corrade is identified by a password and has a certain processing quota. In Corrade, all actions are quantified and restricted by limits such that you can provide hosting to other people by adding their group in Corrade's configuration file.
However, Corrade is not restricted to manipulating groups. Corrade can retrieve region statistics, query primitives for information, grab particles from any primitive, get the
UUID of textures on a primitive, teleport around to other regions, change the estate covenant, sit down and trigger an animation, talk in a group, in local chat, send instant messages, post to Twitter and Facebook, use its artificial intelligence module to converse with other avatars and many, many more functions to explore. Due to the notification feature, Corrade can also act as an asynchronous event catcher, sending events such as group chat, instant messages, money balance changes over HTTP POST to either web-servers or in-world LSL scripts listening to requests via
Some people claim Corrade is the “best bot on the grid” - however, we beg to differ because we see Corrade as a different approach to scripted agents (bots). Here is a comparison of what we consider a “different approach” to other players in the industry:
It is important to understand that Corrade is not an end-product - you cannot expect to walk in a shop that sells car components and ask to buy a car: we will tell you to go to a car dealer instead! Following the analogy, Corrade's target audience consists of programmers (whether in-world LSL or others). Programmers will take Corrade as a component and will create an end-product for you.
We do provide some scripting templates in the Corrade store, as well as HTTP templates, that are closer to an end-product - for instance, the Corrade HUD is a pretty functional tool if you want a pet in a Linden-based grid (yet it only implements a fraction of Corrade's capabilities); similarly, we also develop Vassal that is a land / estate manager. Nevertheless, all of these tools can be changed or created differently (or better) by a programmer that interfaces with Corrade. As for coverage, if you want a particular targeted application that would require a scripted agent, then chances are that a programmer could create one for you using Corrade.
If you do not care about setting up a bot, or if you do not have the means to run one, there are some in-world retailers that we know about that provide Corrade bots:
The Corrade project uses trac as a project managing tool - if you have a feature request or would like to file a bug please use the Corrade ticket system - it does not even require you to sign-up, but if you provide a valid E-Mail address, progress on your request will be mailed to the address you provided.
mono- note that Corrade does not perform well under
monoand you are advised to use Windows instead.
Given the benchmarks and out of experience, the best operating system to run Corrade on is a stripped-down version of Windows typically created for embedded devices:
For previous version please see the archived binaries page.
The Corrade source is hosted using Subversion.
This section tracks third-party developments that include Corrade as part of their system.
Since version 0.91, Corrade is supported by CasperTech as an OpenSource alternative. You can find details about setting up Corrade with CasperTech on their official website.
You can find scripting templates (that also function as test harnesses) in Corrade's store on the Second Life marketplace:
they are demonstration scripts that could provide you with a starting base for programming with Corrade.
By using Corrade's HTTP interface you can pull data from outside of SL without using LSL and by using any programming or scripting language you can think of. In this section you can find various template programs that are built on-top of Corrade which are free to use, adapt, share and even commercialise as part of your own projects under the GNU GPLv3 public license.
The following website contains some demonstrations that show how data can be pulled and processed outside of the grid by using Corrade's HTTP interface.
Configurator.exeto configure Corrade. If this is the first time using the Configurator, then press the
Load...button and load the provided
Corrade.ini. Then you can just change the configuration. For Corrade to be able to interact with scripts, you will need to set-up a group (this can be done both in the
Configurator.exeprogram, or by hand) that exists in the grid (ie: SecondLife) you are connecting to. The UUID, group name and group password are essential to getting Corrade to respond to scripts.
Configurator.exein the main folder and then the Configurator should load up.
mono Configurator.exein order to load the configurator.
Utilities->Terminaland change directory to Corrade's directory and then issue the command:
mono Configurator.exein order to load the configurator.
Corrade.exefile and the bot starts in interactive mode
mono-service -l:Corrade.exe.lock Corrade.exe
Utilities->Terminal, then change directory to the Corrade folder and issue:
mono-service -l:Corrade.exe.lock Corrade.exe.
The application programming interface can be found on a separate page and describes all the commands that can be sent to Corrade along with examples.

We present the various attack vectors on Corrade as well as mitigating them on the Corrade security page. Please revise this en-large to make sure that Corrade is secured properly.
For performance improvements please see the Corrade performance page.
Please see the frequently asked questions page.
Since Corrade needs a server to run on, there are multiple online services providing the means to do so. You can of course run Corrade on your own computer at no cost - since that is what the Corrade project aimed at, but there are online services that can take away the pain of administrating a server by yourself. We list some of these services: some free, some commercial, some affiliated with SL, etc... In case you know other hosting providers, or if you are a hosting provider that offers Corrade hosting (we are particularly looking for a hosting provider that is aware of SL and offers Corrade bots for leasing), please contact us and we will add you.
Docker is a free service for one private repository (root-jail), and up to USD7 per month for 5 private repositories (you can find more information on the Docker pricing page.
The Corrade conservative branch is available on Docker and kindly provided as a project by Kovu Kumel. Corrade is hosted in the
iconmeta/corrade Docker registry and can be found at:

If you need help with Corrade (installing, setting up, general questions), we can be contacted in the following ways, in order of preference:
please note that regardless whether the Earth is a disc or a sphere, the deceptive simulation, respectively the Earth's revolution around its axis, makes it unlikely for your request to be answered immediately.
The best choice, in emergency situations, is to attempt to ask your question in-world in the SecondLife Corrade support group. Otherwise, E-Mailing us would be best.
