Krainode | JSON-RPC Playground

Instantly test, debug, and compare blockchain RPCs, all in your browser.

Multi-chain: Base, Arbitrum, Ethereum, Optimism and more

This is krainode

[Emmanuel @chris__emma]

KraiNode is a browser-based tool that lets blockchain developers instantly test, debug, and compare RPC calls, like Postman but for Web3. The blockchain infrastructure market is growing fast, with millions of developers. Since launch, KraiNode has reached over 200 monthly active users. It’s open source and built to make blockchain development simpler and more reliable.

Funny enough...

@krainode_web3 wasn't planned.

It started because I kept opening Postman whenever I wanted to debug RPC calls.

Then I thought:

"Why isn't there a Postman that's actually built for blockchain developers?"

So I started building one.

After running blockchain nodes in production, I noticed something.

When an RPC starts failing, most developers don't know whether the problem is:

• their code
• their provider
• the chain
• or the node itself

@krainode_web3 exists to remove that guesswork.

Been quiet here for a while.

I've been spending most of my time building infrastructure instead of tweeting.

One of those projects is KraiNode.

Think of it as a developer playground for JSON-RPC.

- Test endpoints.
- Compare providers.
- Inspect raw requests & responses.
- Measure latency.

I originally built it because I got tired of debugging RPC issues across production systems.

We are just getting started 🔥

[Emmanuel @chris__emma]

I just added:
- @BNBCHAIN
- @OPBNB_Network
- @PulseChain
- @SonicLabs
- @taikoxyz

(Mainnets + testnets) to @krainode_web3

Not because “more chains = cool”(well it is 😂 )
But because devs need:

– A fast way to test RPC behavior
– A neutral playground to compare endpoints
– A simple way to debug chain-specific quirks

Just dropped off a call with a a fellow web3 infra guy(very popular in the space), and i have to say it was nice discussing Blockchain nodes.

I still think web3 teams are underrating RPC providers(the dedication they put in to achieve their SLA and SLOs is massive🔥🔥🙌

My BASEline stat shows I need somETHing to stay OPtimistic. Too many HYPEs nowadays, what’s the SOLution chat?

Check out this article by founder of Krainode

[Emmanuel @chris__emma]

Wrote a short guide on running a @tempo testnet RPC node on @ubuntu .

Covers:
• systemd-managed node
• #Prometheus + @grafana metrics
• RPC sync checks
• a tiny status page to track health

If you test the new chains, let me know how it feels.

Who else wants to know their total balance across all their wallets?

Let's say you want today's PnL for all your crypto holdings across different wallets..........that's why I built a lite app to show you exactly that.

Built with Python FastAPI + @DuneSim API (really awesome stuff).
