opendev

Visual transaction debugger and CU profiler for Solana.

opendev takes any Solana transaction signature (or an unsigned base64 blob) and turns it into a fully decoded execution profile — compute unit usage, CPI call trees, account state changes, transfer breakdowns, and an insight layer that flags bottlenecks automatically.

Install

Easiest — via npm (any OS with Node.js 20+):

npm install -g opendevtool
opendev --version

Note: package is named opendevtool on npm (unqualified opendev was taken). The binary it installs is still opendev.

Or, one-liner for Linux / macOS / WSL (sets up Node 20 via nvm if missing):

curl -fsSL https://raw.githubusercontent.com/OpenSubmissionn/Open_DevTool/main/install.sh | sh

Or, from source:

git clone https://github.com/OpenSubmissionn/Open_DevTool.git
cd Open_DevTool
npm install
npm run build --workspace cli
cd cli && npm install -g . --ignore-scripts

For local development with hot-reload:

git clone https://github.com/OpenSubmissionn/Open_DevTool.git
cd Open_DevTool
npm install
npm run build
npm link

That makes opendev point at your working tree.

Quickstart

Analyze a confirmed transaction on mainnet:

opendev tx <SIGNATURE>

Analyze on devnet:

opendev tx <SIGNATURE> --network devnet

Output as JSON:

opendev tx <SIGNATURE> --json

Save a CSV report:

opendev tx <SIGNATURE> --csv --output ./report.csv

Simulate a transaction that has not been broadcast yet (base64 blob or path to a file containing one):

opendev simulate <BASE64_TX>
opendev simulate ./my-tx.b64

Commands

| Command | Description | |---|---| | opendev tx <signature> | Full analysis of a confirmed transaction | | opendev simulate <input> | Simulate an unsigned transaction (base64 blob or file path) | | opendev batch <file> | Run analysis over a list of signatures | | opendev info | Show registered programs and decoder coverage | | opendev login [provider] | Browser-assisted setup for AI insights (default: groq) | | opendev config set-key <provider> <key> | Save an AI provider key from a script | | opendev config get-key [provider] | List configured keys (masked) and their source | | opendev config remove-key <provider> | Delete a key from the credential store | | opendev config set-rpc <url> | Set the default Solana RPC URL |

Run opendev <command> --help for the full flag list.

Common flags

| Flag | Default | Description | |---|---|---| | --network <name> | mainnet | mainnet or devnet | | --rpc <url> | — | Custom RPC URL (overrides --network) | | --json | false | Output as machine-readable JSON | | --csv | false | Save a CSV report | | --output <path> | — | Output file path | | --verbose | false | Enable debug logging |

AI insights (optional)

opendev ships rule-based insights by default. To add AI-generated optimization suggestions, get a free key from console.groq.com/keys (no credit card) or a paid one from console.anthropic.com, then:

opendev login              # browser opens, paste key, gets validated, saved

Keys live in ~/.opendev/credentials.json (chmod 600). For scripted setup:

opendev config set-key groq gsk_xxxxxxxxxxxxxxxx
opendev config get-key                       # confirm

Shell GROQ_API_KEY / ANTHROPIC_API_KEY exports still work and take precedence.

Configuration

To use a custom RPC by default, set OPEN_RPC_URL in your environment:

export OPEN_RPC_URL=https://your-rpc.example.com
opendev tx <SIGNATURE>
