Free tools
The checks we run before a launch, published.
Each tool asks for nothing and keeps your inputs in your browser. Two of them send a domain or server URL to our server to fetch public files; the rest read live data only where they need it. They are the working versions of what the delivery team uses on a Solana or agent engagement.
14 tools
Solana tools
Rent, fees, launch budget, program addresses, IDLs, and the checks a program should pass before it holds other people’s money.
01
Solana cost calculator
Rent for any account size, the fee for a transaction at a given compute budget and priority, and a launch budget, from live mainnet numbers.
Open tool02
Interactive Solana launch checklist
The twenty-six mainnet launch checks with saved progress, a readiness score, and an export of the open items as Markdown.
Open tool03
Solana pre-audit readiness score
Twelve questions about authorities, account validation, tests, and operations that return a readiness grade and the three gaps to close before an audit.
Open tool04
Anchor IDL inspector and PDA finder
Paste an Anchor IDL or a program id, browse instructions and account layouts, and derive program addresses from their seeds, in the browser.
Open tool05
Solana rent calculator
The rent-exempt minimum for any account size in SOL and USD, read live from mainnet, with presets for token accounts, mints, metadata, and Anchor structs.
Open tool06
Solana priority fee calculator
Compute units times micro-lamport price, plus base fee and Jito tip, with live percentiles for any account and for busy DEX and launchpad accounts.
Open tool07
Anchor discriminator calculator
The 8-byte discriminator for any Anchor instruction, account, or event name, as hex, bytes, and base58, computed in the browser.
Open tool08
Solana address checker
Paste any address: valid base58 or not, 32 bytes or not, on the ed25519 curve (a key could exist) or off it (no key can), with hex and byte views and known program ids.
Open tool09
Lamports to SOL converter
Convert lamports, SOL, and USD both ways with the live SOL price, plus micro-lamports per compute unit for fee math.
Open tool10
Solana epoch countdown
The current epoch, slot, percent complete, and the estimated time to the next epoch from live slot timing on mainnet.
Open tool11
Token-2022 extension planner
Pick Token-2022 extensions for a mint, see which ones every holder account inherits, and get the exact account sizes and rent in SOL and USD from live mainnet numbers.
Open tool12
Solana transaction inspector
Paste a signature: fee paid, priority fee and compute units, Jito tip if any, every instruction with its program named, and the logs, in plain words.
Open tool13
Solana account decoder
Paste any account address: owner, lamports, size, rent status, and for Anchor accounts the fields decoded with the program’s on-chain IDL, plus token accounts and mints read natively.
Open tool14
Solana RPC latency checker
Measure an RPC endpoint from our server: response time for getHealth, getSlot, and getLatestBlockhash, and how many slots it lags the public cluster.

4 tools
AI agent tools
What an agent loop costs to run, what an MCP server exposes, whether an agent is ready for users, and whether a site is readable by assistants.
01
AI agent cost calculator
Cost per task and per month for an agent loop: steps, tokens in and out per step, tool calls, retries, cache hits, across current Claude, OpenAI, and Gemini prices.
Open tool02
MCP server inspector
Paste a public MCP server URL: see its tools, input schemas, and capabilities, and observations a production build acts on, such as anonymous access, unbounded inputs, and no rate-limit headers.
Open tool03
AI agent production readiness score
Twelve questions on evaluation sets, guardrails, permission boundaries, cost caps, and audit trails that return a readiness grade and the three gaps to close before an agent goes live.
Open tool04
llms.txt checker and generator
Check whether a domain publishes llms.txt and whether it parses, then generate a draft from the sitemap for the pages you want assistants to read first.
Open tool
None of these tools audits, certifies, or makes a safety claim about a program, an agent, or a server. They surface numbers and open questions; the answers are still engineering work.
