Hello, everyone!
I would like to introduce Astrograph (https://github.com/mobius-network/astrograph) - Stellar GraphQL server.
For now, it supports basic queries for current ledger state (except offers) and subscriptions to basic events like a change of account balance.
We plan to use this service as the replacement for Horizon server in next version of our OSS Mobius Wallet (https://github.com/mobius-network/wallet). Besides that, we are working on historical state navigation and implementing of other type entities and corresponding events (such as effects, operations, etc).
The playground is located at https://graphql.mobius.network/.
We would appreciate any feedback feature requests and PRs. If you have any ideas on use cases we must cover first - let us know by opening an issue.
Thanks.
